library. As the value suggests, this allows the library to be built repeatably;
without this flag, gcc uses a random value in its parsing.
Since the random seed is only used when handling files which do not have any
externally-visible symbols, this change is not needed for any other libraries
in the FreeBSD base system.

shared library being built for amd64. The problem is that libstdc++.so
is produced with 'cc -shared'. This has an internal -lgcc, which is
not PIC. libstdc++.so uses exceptions and the dwarf2 unwinder, which
are in libgcc.a. As a result, non-PIC code gets pulled into libstdc++.so.
This is fatal on amd64 when certain relocation types cannot be used in
PIC mode. The official FSF solution to this is to have libgcc.so with
internal ELF symbol versioning to solve the ABI problem, but I dont want
to fight that battle yet. I tried making libgcc_pic.a (which worked
fine), but thats not something for the 11th hour before a release.

to work at least for the non-hairy stuff. The main wrinkle here is that
a whole mess of include files get installed and under different names.
An earlier version of this built a shadow include tree first in the obj
directory, but this depends on the 'make includes' functionality.
More tweaking is certainly going to be needed.
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".
aren't needed as those files aren't part of libstdc++ any longer. Another
isn't needed as Cygnus doesn't compile with -frtti.
Noticed by: bde & my initial mispelling of ".So".
I knew better... too dependant on the environment we generate in, but...
This fixes the
/usr/lib/libstdc++.so: undefined reference to `filebuf virtual table'
/usr/lib/libstdc++.so: undefined reference to `stdiobuf virtual table'
errors seen after the initial bootstrap from gcc 2.7.2 to EGCS.

than ".so". The old extension conflicted with well-established
naming conventions for dynamically loadable modules.
The "clean" targets continue to remove ".so" files too, to deal with
old systems.
shared versions should not need to add -lm unless the program uses libm
itself. Strictly speaking, libg++ depends on libstdc++, but libstdc++
has dynamic dependencies on some exception tables and binutils doesn't
seem to like it when a secondary library has undefined references. It
doesn't seem to care when -lstdc++ is added on the command line to ld
though. Anyway, the c++ driver adds -lstdc++ explicitly, so that should
be OK. c++ also adds -lm explicitly too, even though it wouldn't need
to now. [except for statically linked binaries as .a files don't have an
equivalent of automatic internal shared object dependencies.]
fix of putting generated source files in SRCS breaks many special
cases (many dependencies had to be incomplete for ${.ALLSRC}
not to give .h files that would break compiling with c++ -c).
Reduce these special cases to the general case so that SRCS works
normally and bsd.lib.mk handles most of the complications. Now
we only have to duplicate rules from bsd.lib.mk to add special
CFLAGS in some cases.
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.
This closes PR#1975 and was on my TODO list, so I'm breaking my own "no more
commits before I fly!" rule and taking care of this, since it was at the
very top and Peter shamed me in to taking care of it. This is definitely
a 2.2 candidate.
