For some reason, the configure test
echo '.text; foo: nop; .data; .long foo-.; .text' > conftest.s

AC_DEFINE(HAVE_AS_X86_PCREL, 1,
[Define if your assembler supports PC relative relocs.])
fails on darwin. Which leads to
#ifdef HAVE_AS_X86_PCREL
# define PCREL(X) X - .
#else
# define PCREL(X) X@rel
#endif
which leads to the error. Curiously, "X-." does seem to work on Darwin,
and you ought to be able to get sysv.S to compile if you edit that ifdef.
If you could figure out why the assembly works, but the configure test
doesn't, that'd be great.
