Not sure.  I don't have access to 10.4 (and 10.5) yet.

gcc version 3.3 20030304 (Apple Computer, Inc. build 1671)

Yes.  Generic _setjmp() code seems to work with a instantaneous test.
But I'm not sure this is appropriate for Darwin ppc.  In gc6.8,
_GC_push_regs() in powerpc_darwin_mach_dep.s is used from
GC_push_roots() in mark_rts.c.
