Can you find out whether the Mac linker has an option to ignore
duplicate symbols (at least for the case where none of the symbols are
actually being imported)?

If it does, adding that switch to the definition of SHLIB_LD in
SC_CONFIG_CFLAGS (in aclocal.m4) is the appropriate solution.

If it doesn't, I can give these functions/variables unique names, but
that's really just a workaround; this issue is likely to crop up again
in the future.
