--- Comment #2 from Matthias Klose <doko at gcc dot gnu.org> 2012-05-28 06:42:37 UTC --- the patch is incomplete. the patch from glibc is found at http://sourceware.org/git/?p=glibc.git;a=patch;h=7dc6bd90c569c49807462b0740b18e32fab4d8b7 using anonymous unions which cannot be used for stage1. The original patch is http://sourceware.org/ml/libc-alpha/2011-07/msg00085.html A third approach from gnulib is pointed out in http://sourceware.org/ml/libc-alpha/2011-07/msg00093.html
