I tried to apply the patch to binutils-2.20.51 and patch said it looked like the patch was applied already so I did NOT apply it. Did I blow it? Must I apply the patch to another version? cs -- http://sourceware.org/bugzilla/show_bug.cgi?id=10924 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
