Fix buildworld -DNO_CLEAN when using with Perforce, which marks files as
read-only by default, meaning files copied can't be overwritten next time.

Update to readline 5.0

Add bmake glue for gdb 6.1.1. Supports alpha, amd64, i386, ia64
and sparc64.

Note that the debugger doesn't support threading, nor kernel
debugging yet.

Reconnect gdb info file to the build.

Upgrade for readline 4.2

A bandaid to try and make this buildable. This should probably be
rechecked by somebody who knows what is meant to happen here. The new
libreadline rluser.texinfo file duplicates the '@defcodeindex bt' entry.

Remove old bmake framework for gdb. It has moved to live next to binutils.

Oops, This should have been committed with the Makefile change that
requires the new file.

Fixed stale near-copy of contrib/libreadline/doc/hsuser.texinfo. Patch
it at build ntime, and only keep the patch for it here.

Don't keep a copy of contrib/gdb/gdb/doc/all-cfg.texi here. Link to it
at build time.

Fixed dependencies.

Removed -I path to gdb's readline. This didn't do much in -current
because the -I path to config/libreadline had precedence, but in
2.2 it help hide the bug that the -I path to the non-contrib
libreadline was garbage.

gdb.info still needs a near-copy of hsuser.texinfo to avoid the
reference to the programming manual. Use this near-copy of the version
of hsuser.texinfo in contrib/libreadline instead of the stale near-copy
in contrib/gdb.

Simplify it using SRCDIR

changes required in the doc directory for making the gdb info
files using the texi sources in /usr/src/contrib/gdb/gdb/doc.

I put a pointer to /usr/src/contrib/libreadline/doc into
Makefile.inc in the hope that the appropriate files would be
picked up.

This is based on /usr/ports/devel/gdb.

2.2 candidate ?

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Fix path to readline docs, since it's now in contrib

Same deal.

Fix bogosity with gdb documentation path.

GDB-4.12 from ports with support for shlibs but not the kernel.

This is a greatly pared down version of the full gdb-4.12, all the
config stuff has been removed and the supporting libraries have
been stripped to a minimum. This is a 1.1.5 only port, I'll do a
more complete port for 2.0 which will have all the config stuff
and will install the gnu support libraries as system libraries like
we do for readline.

There wasn't much point for 1.1.5 since only gdb would use them so I
went for saving space instead. For 2.0 I'll config all the
other gnu tools to use them as well.
