-----------------------------------------+------------------------------
 On Arch Linux with boost 1.54.0, I'm getting
 locale::facet::_S_create_c_locale name not valid when calling
 boost::path::root_directory() while LANG is set to a locale which is
 unlisted in locale -a.

 boost_file_system_test.cpp:
 {{{
 #include <boost/filesystem.hpp>
 int main() {
   boost::filesystem::path("/abc").root_directory();
 }
 }}}

 Compiling, running and backtrace:
 {{{
 $ g++ -std=c++0x -I/usr/include -lboost_filesystem -lboost_system -o
 boost_filesystem_test boost_file_system_test.cpp

 $ LANG=foo gdb boost_file_system_test
 ...
