I was working on ports of gcc-2.7.2 and libg++-2.7.1 for a while. I got
interrupted and put it down, unfortunately. But maybe I can put you on
the right track. (Note: I haven't looked at the pgcc stuff.)
The way to get rid of the weak symbols is to delete these lines from
"config/i386/freebsd.h":
#define ASM_WEAKEN_LABEL(FILE,NAME) \
do { fputs ("\t.weak\t", FILE); assemble_name (FILE, NAME); \
fputc ('\n', FILE); } while (0)
Just delete them; that's all you have to do. After that, everything
should work fine with our standard assembler and linker.

Right. Don't waste your time on the GNU binutils linker. FreeBSD
support is MILES away. For starters, there is absolutely _no_ support
for our shared libraries in it.

Don't use binutils. Just make the compiler change to get rid of weak
symbols, and use the standard FreeBSD assembler and linker.

We didn't go off in left field with our linker. It's just old, that's
all. We stayed in one place, while GNU went off somewhere else (left
field?). I dearly wish that GNU binutils had up-to-date FreeBSD
support, but it doesn't. It would take a _lot_ of work to put it in.
