Joseph S Myers just replied to my post on the gcc mailing list, about
this:
http://www.nabble.com/Re%3A-wot-to-do-with-the-Maverick-Crunch-patches--p16397272.html
gcc 4.2.2 doesn't have the patch for iwmmxt unwind support applied:
http://gcc.gnu.org/ml/gcc-patches/2007-01/msg00049.html
It should be in gcc 4.3.0.
binutils 2.18 should have this patch applied already:
http://sourceware.org/ml/binutils/2006-08/msg00207.html
binutils 2.17 doesn't have the patch applied.
