Also:
Switch FreeBSD to use libgcc_s.so.1.
Use dl_iterate_phdr to locate shared objects' exception frame
info instead of depending on older register_frame_info machinery.
This allows us to avoid depending on libgcc_s.so.1 in binaries
that do not use exception handling directly. As an additional
benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.
Build newly added libgomp.so.1 library, the runtime support
bits for OpenMP.
Build LGPLed libssp library. Our libc provides our own
BSD-licensed SSP callbacks implementation, so this library
is only built to benefit applications that have hadcoded
knowledge of libssp.so and libssp_nonshared.a. When linked
in from command line, these libraries override libc
implementation.
cc1plus can apparently be built if you happen to have
/usr/bin/gperf, or set CXX to point to a C++ compiler
that can build gperf(1) in the bootstrap-tools stage
of buildworld.
collect2 was added based on the need of -frepo. However, -frepo is currently
broken on -CURRENT (Gcc 2.95.4 20020320 [FreeBSD] / ld 2.12.0 [FreeBSD]
2002-04-10). It is also broken on RELENG_4 (Gcc 2.95.3 20010315 / ld
2.11.2 20010719), so there is no need to MFC collect2 there yet. I have
a feeling the brokeness is due to the wide difference between the libiberty
bits of Gcc 2.95 and the later ld.

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.
it's and useful. (Ever tried to read 'nm' and 'ldd -v' output on a c++
object or library? :-) This filter decodes the mangled symbol names.)

(the old cc has been tagged with "gcc_2_6_3_final" so we have a reference
point in case of unforseen disasters...)
This has the objc backend active, and I think I've managed to get the
f77 f2c support through in one piece, but I don't know fortran to test it.
A 'make world' change and libobjc commit will follow.
If you normally do 'make -DNOCLEAN world', do not do so this time, I know
it can fail with groff.
This version of gcc makes a **LOT** more warnings on our kernel.
Notice that the libgcc DOESN'T change number, because there are no
changes.
Also now the gnu2bmake stuff is synchronized again.
I commit this so that others can test too.
You might want to postpone any "make worlds" until tomorrow, to
avoid any problems I didn't see in the first pass.
Thanks to Bruce for rounding up our changes to gcc.
no longer link against the whole library, since they don't require much
from it, but just compile the few small modules they actually need static.
This should save a measurable amount of space; compare:
-r-xr-xr-x 1 bin bin 155648 Sep 18 18:00 cc1*
-r-xr-xr-x 1 root bin 1048576 Sep 18 17:33 cc1.noshae*
Of course, the library takes up a bit of space, but when you add in the
savings from the C++ compiler, you more than make up the difference:
-r--r--r-- 1 bin bin 1157344 Sep 18 18:27 /usr/lib/libcc_int.so.26.0
-r-xr-xr-x 1 bin bin 491520 Sep 18 18:27 /usr/libexec/cc1plus*
