% cat t.c

% cat t.cc
#include <assert.h>
extern "C" int f(int);
int f(int a)

% g++ -dynamiclib t.cc -o libt1.dylib
% gcc -dynamiclib t.c -o libt.dylib
% g++ -L. -lt -lt1 main.cc
Before my patch to use shared libgcc for dynamic library which means we are doing something wrong:
/usr/bin/ld: warning suggest use of -bind_at_load, as lazy binding may result in errors or different
symbols being used
symbol ___eprintf used from dynamic library /Users/pinskia/tree-cleanup-branch/lib/gcc/powerpc-
apple-darwin7.4.1/4.1.0-tcb/../../../libstdc++.dylib(_eprintf.o) not from earlier dynamic library
libt.dylib(_eprintf.o)
After (when linking the first dynamic library):
ld: Undefined symbols:
___eprintf
/usr/bin/libtool: internal link edit command failed

Patch here: <http://gcc.gnu.org/ml/gcc-patches/2004-11/msg00515.html>, I have a new assert.h
which corrects the problem with not outputting the function name (this was also broken in darwin's
headers anyways).

The patch is still slightly wrong, the real way to fix it would be to add -lgcc and make sure that the
static libgcc's sources are pritave_extern (aka hidden and like on linux is right now).

Patch here: <http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02176.html> (Zack posted this but I
am keeping my self assigned as I am the one who caused the regression to get to this point).
