Author: andrew Date: Tue Dec 25 07:37:33 2012 New Revision: 244673 URL: http://svnweb.freebsd.org/changeset/base/244673 Log: Fix the __glibcxx_min and __glibcxx_max macros for a signed wchar_t. * The __glibcxx_max macro came from GCC svn r138078, the last GPLv2 revision of this file. * I wrote the updated __glibcxx_min macro.
