Are you running SuSE 7.1?  In that case you need gcc 2.95.3 or extra
patches for gcc (see the SuSE source rpm for what we ship) to work
with glibc 2.2.

s_copy is part of libg2c.a:
$ nm /usr/lib/gcc-lib/i486-suse-linux/2.95.2/libg2c.a |grep copy
000000e0 t copy
         U s_copy
s_copy.o:
00000000 T s_copy
         U s_copy
         U s_copy
         U s_copy
         U s_copy
         U s_copy
         U s_copy
         U s_copy

The other functions that are missing are also part of libg2c, so you
should link against that library.

We don't break GCC on purpose ;-).
