  Apparently this variable is shared with the C file clocale.c, so I
  think it makes sense that there can be problems. Although I am not
  sure the standard allows the C++ compiler to mangle the names of
  arrays (only functions).

Could an
  extern "C"
cause problems for standard conforming compilers?
