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.
'target'. Latter is problematic in particular as apparently FreeBSD's
bsd.prog.mk re-defines it under some circumstances. This causes an
unexpected failures like -dumpmachine not working for cc while working
fine for c++.
Do not re-define IN_GCC in multipe places, it gets inherited from
Makefile.in anyway.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.
Tested on: i386 (extensively), alpha
This thing grew. We now have to link with many more files as if it
were one of the driver programs. We also have to deal with the very
irritating layering of malloc and friends. Our malloc works *very*
well thank you. Thus we will use it.
was installed in /usr/bin normally got clobbered when objformat
was installed. Indirection through objformat is correct although
underscore handling is the only thing that differs for aout and
elf -- going through objformat is the easiest way to set c++filt's
underscore handling flag correctly.
They have been bootstrapped by `make world' since long before the
hacks here were cloned from ../libgcc/Makefile. The versions just
built in "../*" normally won't work if the target system is not binary
compatible.
Don't use OBJS to defeat `make depend'; just put generated sources in
SRCS.
Added temporary files to CLEANFILES.
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.)
