[cfe-commits] [libcxx] r135035 - in /libcxx/trunk: include/__config include/locale src/locale.cpp

Author: coppro
Date: Wed Jul 13 01:40:50 2011
New Revision: 135035

URL: http://llvm.org/viewvc/llvm-project?rev=135035&view=rev
Log:
Implement the __nolocale functions properly so that they will work on
all platforms. Unfortunately a lot of this remains conditionally
compiled so as not to break Apple's ABI.

The new _LIBCPP_LOCALE__L_EXTENSIONS macro can be defined on other
platforms that support _l suffixes for all functions in order to use
them.
