 I have came across the same problem, only I am using a cross compiler. The
 true issue lies in how GCC (libstdc++) is configured. On some Linux
 distributions and apparently FreeBSD, the C++ runtime is configured to use
 generic locale support. This is the one that handles nothing but "C".
 However, if one configures GCC with "--enable-clocale=gnu", a more
 advanced implementation becomes available. I don't know if it's tied in
 any way to the GNU C library (it doesn't appear to) and I also don't know
 the proper way to check if you have "generic" or "gnu" enabled. I used

 {{{
 #!sh
 $ objdump -D -C -j .text -M intel libstdc++.so.6 >libstdc++.so.6.S
 }}}

 to look in the assembler dump for _S_create_c_locale(). A call to
 "newlocale_at_plt" tells me I have "gnu" enabled.
