Remove info pages

Connect libgnuregex 2.17 to the build.

Bump the version of all non-symbol-versioned shared libraries in
preparation for 8.0-RELEASE. Add the previous version of those
libraries to ObsoleteFiles.inc and bump __FreeBSD_Version.

Update build infrastructure for new GNU regex bits.

Style.

Be explicit about which regex.h file we are including. This reduces the
need for hack workarounds in tools/lib32/build32.sh.

Forced commit note to explain why NO_POSIX_COMPAT was removed with upgrade.

NO_POSIX_COMPAT was added in 1996 as attempt to resolve POSIX regex
functions conflict for fixit floppy (they are both in libc and libgnuregex)
The way it done (simple excluding POSIX functions from compile) breaks
legitimate case when, say, some program from ports calls both POSIX
and GNU regex functions (it will call POSIX ones from libc and fails,
because header <regex.h> is from GNU).

Now our fixit floppy (and other crunched floppies, as I check) not
use libgnuregex, so the hack can be removed.

Upgrade to regex from grep 2.4.2

Install gnuregex.h as wrapper for gnu/regex.h (with warning)

Install regex.h under include/gnu

Zap now-unused SHLIB_MINOR

Added new bsd.incs.mk which handles installing of header files
via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files. Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.

Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1. Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):

kerberos5/lib/libtelnet/Makefile
lib/libbz2/Makefile
lib/libdevinfo/Makefile
lib/libform/Makefile
lib/libisc/Makefile
lib/libmenu/Makefile
lib/libmilter/Makefile
lib/libpanel/Makefile

Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.

Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD. Similarly for INCOWN, INCGRP,
and INCMODE.

Consistently use INCLUDEDIR instead of /usr/include.

gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.

These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".

$Header$ -> $FreeBSD$

Commit msg for rev 1.20 should probably have added that gnu/lib/libregex was
the only lib that was using the SHLIB_* values from gnu/lib/Makefile.inc.
Thus I simply added the to the Makefile here.

Makefile.inc was politing all subdir's with SHLIB_{MAJOR,MINOR} definitions.
Since we aren't keeping all the GNU libs at the same versions, this is
useless and causes us to build a shared libgcc, which we don't want to do.

Disable the inclusion of the Posix regexp stuff into libgnuregexp.
We've already got it in libc, but both libraries are incompatible
wrt. their header files and internal data structures. This
incompatibility caused the expr(1) on the fixit floppy to mysteriously
dump core for the colon operator.

Strong 2.2 candidate, since it fixes the usage of MAKEDEV on the fixit
floppy. I'd like to get it reviewed by somebody else though.

cmp -s || install -c ==> install -C

Convert to newly aded collate compare function

Use collate for alpha character ranges

Change `install' to `${INSTALL}' so that default install flags can be
specified in the top level Makefiles.

Previously I missed dozens of Makefiles that skip the install after
using `cmp -s' to decide that the install isn't necessary.

Add cmp -s to beforeinstall target

Install the include file in the same way that all other includes file are
in the 'beforeinstall' target.

Add doc to SUBDIR

Upgrade to code which should satisfy all things which we have

Upgrade regex code to most recent that I found
Version number still not changed

Install libregex.h with the correct owner, group and mode.

Remove explicit specification of SHLIB major and minor nos.

A perfectly good libgnuregex.a and you can't use it! No header was being
installed. Do so now as gnuregex.h

No longer install the GNU regex.h include file.

Update shlib version to 1.0

Added
SHLIB_MAJOR=0
SHLIB_MINOR=0

Changed install -o root -g bin to -o ${BINOWN} -g ${BINGRP} on the header
install commands to be consistent with other header files.

Changed afterintall: target to beforeinstall: so that it is easy to get
the regex.h header file installed.
