Comment(by altaic):
The fix for the read_only_relocs warnings the is simple, but I'm having
trouble attaching the patch because it is apparently too large for trac.
I haven't completely sorted out the compact unwind warnings yet-- the OS X
10.6 linker now defaults to creating compact unwinds, which is a good
thing, however the unwind info for `_ffi_call_unix64` can't be represented
in the compact format. Someone more familiar with libffi may be able to
figure out how to make `_ffi_call_unix64` compatible with the compact
unwind format. Otherwise, we may be able to pass the linker
`-no_compact_unwind`, or possibly disable the warnings. Unfortunately, the
option `-warn_compact_unwind` turns the warning ''on'' (which is the
default), and `-no_warn_compact_unwind` does not exist. Furthermore, even
though using `-no_compact_unwind` does turn off the generation of compact
unwinds, for some reason the warnings still pop up when I run the test
suite.
