Ping: http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00429.html
The patch is to fix dependency issue of libgcc Makefile.in by adding 'rm libgcc_tm.stamp' in the clean rule. That was fixed on main trunk (r187838) but not on gcc-4_7-branch. Since gcc-4_7-branch is still open, is it OK to backport r187838 into gcc-4_7-branch? Best regards, jasonwucj
