Hi!

Is it ok to backport
https://github.com/atgreen/libffi/commit/0de3277b18cf54be3b81d509b9be9b47d9bc1e82
fix from upstream to gcc's libffi copy?  The tests fail on various targets.

2013-01-07  Thorsten Glaser <tg@mirbsd.org>

	* testsuite/libffi.call/cls_uchar_va.c,
	testsuite/libffi.call/cls_ushort_va.c,
	testsuite/libffi.call/va_1.c: Testsuite fixes.


	Jakub
