    Fix missing prototype error, void end of function error on Windows.
    
    MinGW64 gcc silently ignores C prototype with no arguments, issuing
    a missing prototype error instead. set_platform_locale must return
    a free-able char* even if all of LC_ALL, LC_MESSAGES, and LANG are
    unset.
