Comment(by chak):
This is fixed by
{{{
commit 30ccc9f39dd2cf1ad14e6116778aa1fd94526c19
Author: Manuel M T Chakravarty c...@cse.unsw.edu.au
Date: Wed Jul 27 23:05:01 2011 +1000
On OS X x86_64, use -Wl,-no_pie and -Wl,-no_compact_unwind to avoid
linker warnings
- -Wl,-no_pie can be removed once GMP gets updated
}}}
on Lion (10.7) with Xcode 4.1. There is still (another) warning on Snow
Leopard. I'd recommend to upgrade your OS.
I wonder whether the warning about the unwinds will go away once we can
compile with clang. In that case, we could remove
-Wl,-no_compact_unwind. We should also be able to remove -Wl,-no_pie
with a newer GMP.
I don't know how this all affects the 32bit build (the patch only applies
to x86_64). Apple basically deprecated 32bit binaries with Lion.
Igloo, do you want to close the bug or leave it open as a reminder. (At
least the priority can be downgraded, I think.)

Comment:
I inquired on the libffi mailing list about an upstream fix and received a
response from the author of libffi, Anthony Green:
{{{
Thanks for these pointers. I read the first thread and my summary is
that the EH unwind info format has changed in OS X 10.6 and GCC hasn't
caught up yet.
I'm not aware of any volunteers planning to update libffi to match this
change, but it sounds like it is required in order to support EH.
Volunteers welcome!
AG
}}}
In the meantime, I hacked out a patch for the testsuite that filters out
the warnings. It's not intended to be any sort of fix for merging, but it
is useful for examining the results of the testsuite until an actual fix
is produced.
