Modified Fri Jul 10 07:44:34 2009 CDT by rafael backport part of http://gcc.gnu.org/ml/gcc-cvs/2007-10/msg00118.html The patch is for libstdc++ and it was GPL2 at the time. Modified Tue Apr 29 01:20:19 2008 CDT by asl Backport from mainline (pre-GPLv3). Fix for sizeof(const void*) > sizeof(unsigned long). Approved by: jhb (mentor) MFC after: 2 weeks
