The open POSIX test suite reveals that sigpause(int sigmask) from
4.2 BSD takes a signal mask as argument while POSIX sigpause(int
sig) expects a single signal. Do not expose our traditional BSD
sigpause(3) to XPG/POSIX sources.

Remove sigreturn declaration and the now-unused libc syscall stub

Convert sigemptyset and sigfillset to inline functions to avoid
warnings with newer gcc versions and -Werror=unused-value.
OK guenther@

Split the intra-thread functionality from kill(2) into its own syscall
thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition. thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel(). Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.

Minor bump to both libc and libpthread: make sure you install a new kernel!

Welcome to 1989: assume the compiler support const

lint is dead (long live the lint!), so stop using it as a cpp conditional
(namespace pollution!) or talking about its opinion on code.

Remove excessive sys/cdefs.h inclusion
ok guenther millert kettenis

Improve standards compliance: bsd_signal() was XSI only and has been dropped
from the most recent version, use the implementation namespace for variables
in inline functions, and add __restrict as specified.

ok millert@

functions are top-level objects anyways, make that clearer.
Okay otto@

The prototype for pthread_sigmask(2) is supposed to live in <signal.h>
instead of <pthread.h>.

ok guenther@, millert@

sigstack() is long dead, and the compat sigaltstack syscall is gone too.
Correct the namespace protections for sigreturn(), sigwait(), and psignal()

ok millert@

sigset_t is unsigned, so eliminate a warning by shifting a 1U instead
of a 1 when creating signal masks.

ok millert@

Now that __only_inline is in <sys/cdefs.h>, replace the local versions in
<ctype.h> and <signal.h>

ok kettenis@ millert@ deraadt@

Always force GNU inline semantics here as well.

Make sure sys_signame and sys_siglist are wrapped in __BEGIN_DECLS.
Needed to tell pedantic C++ compilers these symbols have 'C' linkage.

ok kurt@

allow extern inline stuff to proceed unchanged thru the mess that the
combined GCC and ISO committees managed to make out of it.

With this, gcc >= 4.3 can grok its way through it correctly.

okay kettenis@, with some help figuring stuff out.

Do not declare errno as extern int, set it via __errno().

First step in include files overhaul. Use __FOO_VISIBLE (as defined
in sys/cdefs.h) instead of _FOO_SOURCE. Also fix several namespace
pollution issues, including the byte order defines. OK deraadt@

XPG specifies bsd_signal(3) so make it an alias for signal(3); OK deraadt@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

We live in an ANSI C world. Remove lots of gratuitous #ifdef __STDC__ cruft.

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Add thread-safety to libc, so that libc_r will build (on i386 at least).
All POSIX libc api now there (to P1003.1c/D10)
(more md stuff is needed for other libc/arch/*)
(setlogin is no longer a special syscall)
Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS).
Doc some re-entrant routines
Add libc_r to intro(3)
dig() uses some libc srcs and an extra -I was needed there.
Add more md stuff to libc_r.
Update includes for the pthreads api
