Reorganize _LIBCPP_LOCALE__L_EXTENSIONS Instead of checking _LIBCPP_LOCALE_L_EXTENSIONS all over, instead check it once, and define the various *_l symbols once. The private redirector symbol names are all prefixed with _libcpp_* so that they won't conflict with user symbols, and so they won't conflict with future C library symbols. In particular, glibc likes providing private symbols such as __locale_t, so we should follow a different naming pattern (like _libcpp_*) to avoid problems on that front. Tested on Linux with glibc. Hoping for the best on OSX and the various BSDs. http://reviews.llvm.org/D17456 llvm-svn: 263016

// The BSDs have lots of *_l functions. We don't want to define those symbols

// we will define the mapping from an internal macro to the real BSD symbol.

Add system header pragma to BSD locale fallback headers. This prevent leaking warnings to the user about use of C++11 extensions in C++03. llvm-svn: 309917
