Module Name: src
Committed By: drochner
Date: Thu May 6 10:01:20 UTC 2010
Modified Files:
src/gnu/dist/gcc4/gcc: gthr-posix.h
Log Message:
make the stdc++ headers usable for clang++. clang wants that __weakref__
declarations are "static", gcc-4.1 uses "extern" here.
(gcc-4.2 uses "static" as well, so this looks like a bug in gcc.)
