tools/compat: provide nb_check_cc_flag.m4

Implement m4 macro NB_CHECK_CC_FLAG(FLAG, [VAR=FLAG_DERIVED])
Determine if the C compiler supports FLAG,
and sets output variable VAR to FLAG if FLAG is supported.

If VAR is not provided, default to FLAG_DERIVED, which is
FLAG converted to upper-case and all special characters
replaced with "_", and the result prepended with "CC_".
FLAG_DERIVED is appended to the m4 macro NB_CHECK_CC_FLAG_VARS.
E.g., if FLAG is "-Wexample=yes", FLAG_DERIVED is "CC_WEXAMPLE_YES".

This is implemented in separate buildaux/nb_check_cc_flag.m4,
based on configure's NB_CC_FLAG(), but supports VAR override.

Adapt configure from internal NB_CC_FLAG() to NB_CHECK_CC_FLAG().

(Note: AX_CHECK_COMPILE_FLAG() from autoconf-archive could be enhanced
to support the clang and gcc workarounds I've implemented here.)

tools/compat: support all bsd.own.mk disabled warnings

Check the host CC support for all the warnings now in <bsd.own.mk>
and override appropriately in defs.mk.

In general there's a 1:1 mapping, with the special case
CC_WNO_ADDRESS_OF_PACKED_MEMBER which is set from both
@CC_WNO_ADDRESS_OF_PACKED_MEMBER@ (gcc) and
@CC_WNO_ERROR_ADDRESS_OF_PACKED_MEMBER@ (clang).

tools/compat: disable host CC warnings

Determine if the host CC supports flags to disable various
warnings similar to <bsd.own.mk> GCC_*, CLANG_*, and CC_*,
and override the <bsd.own.mk> equivalents in defs.mk.

Silences "warning: unknown warning option '...'" from our source.
External source (e.g., binutils and gcc) need their own fixes
to enhance their detection of supported clang compiler flags.

tools/compat: detect supported host compiler flags

Define NB_CC_FLAG(FLAG) to use AX_CHECK_COMPILE_FLAG
to determine if the host compiler supports FLAG
and define and AC_SUBST CC_FLAG if so.

Use workarounds to force clang to hard-fail on unknown -Wwarning,
and gcc to use -WWARN to check unknown -Wno-WARN because the
latter doesn't cause an error in gcc.

In the future we could use NB_CC_FLAG([-fcommon]) for
older NetBSD release branches compiled with host gcc 10+.

Rework Darwin -no-cpp-precomp check to use NB_CC_FLAG().
Note: this flag probably hasn't been required on macOS (Darwin)
for a long time, but serves as a good example on how to use this.

Display varaibles at the end of configure to show what was detected.

tools/compat: don't expose HAVE_PTHREAD_H to make

Non of the tools Makefiles needs HAVE_PTHREAD_H, so don't
AC_SUBST it or provide in defs.mk.

tools/compat/configure.ac: style tweaks

Use "NB_" prefix not "AC_" for our macros ("AC_" is for autoconf).
Fail is NB_ macro isn't defined.
Use AC_DEFUN() instead of define().
Consistently use () in zero argument macro calls.

ctfmerge: fix macOS semaphore implementation

Use dispatch_semaphore_create() if present instead of sem_init().

macOS doesn't actually implement sem_init() (et al)
(even though it provides the prototypes as deprecated).
This was detected by the previous commit to ctfmerge
that added error handling.

Implement ctfmerge's barrier operations in terms of
dispatch(3) APIs such as dispatch_semaphore_create() (et al).

Update tools/compat/configure.ac to find dispatch_semaphore_create().

Fixes ctfmerge on macOS hosts.

Make using autoheader easier:
split off the autogenerated file into nbtool_config_internal.h,

This way you can just change configure.ac, run autoconf and autoheader,
verify the result, and commit, but don't have to edit nbtool_config*in
manually every time.

use sys/poll.h and HAVE_SYS_POLL_H instead of just HAVE_POLL_H
HAVE_SYS_POLL_H is used by src/include/roken.h needed by the host tool asn1_compile

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

More properly host-tool-ify stat

As discussed briefly on tech-toolchain, AIX doesn't have "u_long",
so add a check for that. Partial fix for PR toolchain/22177.

Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

Add a putc_unlocked().

Always use NetBSD's fts(3) in compat builds. Some systems (notably
Red Hat 7.3, at least) do not have fts(3) implementations that work

* Check for mkstemp() and mkdtemp(), and build them into libnbcompat
if necessary.
* mktemp is now a host-tool, so nuke the lame script (which isn't even
properly installed during the tools bootstrap).

* Always include the NetBSD glob(3) in libnbcompat, as the host
tools use some features of glob(3) that are not available on
all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
is not really standardized, and the vis(3) present on some systems
is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.
* Update the README to indicate the current state of building the
host tools on Solaris 8 (for SPARC).

Fine-grain checking somewhat:
* check for user_from_uid() in addition to pwcache_userdb()
* check for svis() in addition to vis()

use sys/poll.h and HAVE_SYS_POLL_H instead of just HAVE_POLL_H
HAVE_SYS_POLL_H is used by src/include/roken.h needed by the host tool asn1_compile

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

More properly host-tool-ify stat

As discussed briefly on tech-toolchain, AIX doesn't have "u_long",
so add a check for that. Partial fix for PR toolchain/22177.

Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

Add a putc_unlocked().

Fix the socklen_t test; we need to explcitly list the headers we want
included for that test.

Always use NetBSD's fts(3) in compat builds. Some systems (notably
Red Hat 7.3, at least) do not have fts(3) implementations that work
correctly with -D_FILE_OFFSET_BITS=64.

* Check for mkstemp() and mkdtemp(), and build them into libnbcompat
if necessary.
* mktemp is now a host-tool, so nuke the lame script (which isn't even
properly installed during the tools bootstrap).

* Always include the NetBSD glob(3) in libnbcompat, as the host
tools use some features of glob(3) that are not available on
all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
is not really standardized, and the vis(3) present on some systems
is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.
* Update the README to indicate the current state of building the
host tools on Solaris 8 (for SPARC).

Fine-grain checking somewhat:
* check for user_from_uid() in addition to pwcache_userdb()
* check for svis() in addition to vis()

Redo previous differently: use AH_TOP and AH_BOTTOM macros to insert
header and footer into nbtool_config.h.in directly.

Make using autoheader easier:
split off the autogenerated file into nbtool_config_internal.h,
and let nbtool_config.h be a file with the proper wrappers.

This way you can just change configure.ac, run autoconf and autoheader,
verify the result, and commit, but don't have to edit nbtool_config*in
manually every time.

Add AC_CHECK_DECLS test for strsuftoll. hannken reports it is needed

too.

change #include <sys/endian.h> => #include <machine/endian.h> so that
it's (more) consistent in the tree; this, along with changing tools/compat's
autoconf detection from AC_CHECK_FUNCS to AC_CHECK_DECLS makes the vast
majority of htobe16 and friends' redefinition errors bite the dust.

should fix PR/32878. Tested on NetBSD-current, FreeBSD4, Solaris8.

Redo previous differently: use AH_TOP and AH_BOTTOM macros to insert
header and footer into nbtool_config.h.in directly.

Make using autoheader easier:
split off the autogenerated file into nbtool_config_internal.h,
and let nbtool_config.h be a file with the proper wrappers.

This way you can just change configure.ac, run autoconf and autoheader,
verify the result, and commit, but don't have to edit nbtool_config*in
manually every time.

Add AC_CHECK_DECLS test for strsuftoll. hannken reports it is needed
for building nbmakefs on 3.0/i386.

Use the AC_DEFINE version with three arguments consistently, since
then autoheader works too.
Replace the remaining abusers of AC_CHECK_FUNCS with AC_CHECK_DECLS
too.

change #include <sys/endian.h> => #include <machine/endian.h> so that
it's (more) consistent in the tree; this, along with changing tools/compat's
autoconf detection from AC_CHECK_FUNCS to AC_CHECK_DECLS makes the vast
majority of htobe16 and friends' redefinition errors bite the dust.
Tested with -current and FreeBSD.

touch an empty sys/bswap.h if detected as missing by configure
this fixes cross compile problems from recent changes to
convert machine/bswap.h to sys/bswap.h

Remove commas in AC_CHECK_FUNCS that shouldn't be there.

remove HAVE_STRUCT_STATFS_F_IOSIZE
this is not currently being used and should be replaced with
HAVE_STRUCT_STATVFS_F_IOSIZE, but that will be done separately.
This commit should be able to be safely pulled up to
the netbsd-2-0 branch to address PR toolchain/26415

Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

use sys/poll.h and HAVE_SYS_POLL_H instead of just HAVE_POLL_H
HAVE_SYS_POLL_H is used by src/include/roken.h needed by the host tool asn1_compile

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

More properly host-tool-ify stat

As discussed briefly on tech-toolchain, AIX doesn't have "u_long",
so add a check for that. Partial fix for PR toolchain/22177.

Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

Add a putc_unlocked().

Fix the socklen_t test; we need to explcitly list the headers we want
included for that test.

Check for sys/socket.h and socklen_t.

Include <sys/types.h> before <grp.h>; Mac OS 10.2.2 needs this.

Include <sys/types.h> before including <dirent.h>; Mac OS 10.2.2

- Migrate fparseln(3) from libutil to libc, where it should have been in
the first place...
- Bump libutil major (to 7.0) and libc minor (to 12.91).

replace missing strsuftoll(3)

Just check for poll.h, don't fail if it's not present.

Provide strtoll() in libnbcompat.
Should fix relevant build issue on HP-UX and MacOS X hosts.

check for lchflags

Check for <poll.h> and poll(2).

Always use NetBSD's fts(3) in compat builds. Some systems (notably
Red Hat 7.3, at least) do not have fts(3) implementations that work
correctly with -D_FILE_OFFSET_BITS=64.

* Check for mkstemp() and mkdtemp(), and build them into libnbcompat
if necessary.
* mktemp is now a host-tool, so nuke the lame script (which isn't even
properly installed during the tools bootstrap).

* Always include the NetBSD glob(3) in libnbcompat, as the host
tools use some features of glob(3) that are not available on
all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
is not really standardized, and the vis(3) present on some systems
is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.
* Update the README to indicate the current state of building the
host tools on Solaris 8 (for SPARC).

Fine-grain checking somewhat:
* check for user_from_uid() in addition to pwcache_userdb()
* check for svis() in addition to vis()

Rather than hardcoding two possible locations of the POSIX shell (for
Solaris and everything else), set _PATH_BSHELL to the first occurrence of
"sh" on the path. This should be rather more portable.

Add test for alloca() and <alloca.h>, since Sun Workshop C 5.0 needs this.

Create sys/endian.h if it doesn't exist, since rmd160.c includes it directly.

Emit an empty <stdint.h> if the host doesn't have one. Should fix PR 16416.

Re-add test for <sys/endian.h>; it disappeared somewhere along the way.

Add a stub issetugid() for platforms that don't have it. For now, we assume
that no host program will be installed set-id, so the stub function always
returns 0.

Revert addition of mkdtemp() to libnbcompat. I don't think we need mktemp(1)
after all.

Add mkdtemp to libnbcompat, since glibc doesn't have it an mktemp(1) will

Add the md[245], sha1 and rmd160 functions to libnbcompat, conditional on their
not being in the host libc.
This will be necessary to make cksum into a host tool.

Don't gratuitously touch the replacement headers in ${.OBJDIR}/include;
instead, touch them only if they're changed.

Move inttypes.h to list of auto-generated-empty headers.

Add compat defns for uint*_t (the non-underscored ones).
[The logic in all of this is ugly, and should instead be fixed up to use
AC_CHECK_SIZEOF to use primitives if the counterpart type is unavailable.]

Add some more bits of host compatibility.

Roll in fixes to permit cross-compiling from non-NetBSD hosts. This
round has been tested on Solaris/x86 and Linux hosts.

* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.

Make almost all tools compile and run properly on non-NetBSD hosts. (In
particular, most tools now run correctly on Solaris 7.)

- Replace pwcache(3) if necessary (pwcache_userdb(3) is checked for).
Tested on -current and 1.5.3.
- Wrap some long lines.

Make many host tools compile on non-NetBSD hosts. Not complete, but
very nearly there.

look for <inttypes.h> and #include if found (for uint*_t)

Add replacement fgetln(3) (from lukemftp/libukem), as fparseln(3) uses it

Add the framework for autoconf-based src/tools/compat structure. This will
(after it is more fleshed out) allow the host tools to work more cleanly
on non-NetBSD hosts.

Update tools/compat/configure for new path of "rpc/types.h".

Remove intermediate patch from rpcgen/Makefile.
