--- Comment #2 from Joel Sherrill <joel at gcc dot gnu.org> 2011-12-14 18:26:11 UTC --- Stuart Henderson sent this in response to my status report to gcc@ mailing list. This looks like a known, general issue which Bernd had a fix for, but it doesn't appear to have been checked in yet: http://gcc.gnu.org/ml/gcc-patches/2011-11/msg01524.html This appears to let the build get further since it is now generating invalid assembly building newlib.
