MinGW MSVCRT has non-standard vswprintf() (for MSVC compatibility
presumably) and normally _vsnwprintf() is used instead
mingw32 normally uses MSVCRT which has non-standard vswprintf() and so
normally _vsnwprintf() is used instead, the only exception is when mingw32
is used with STLPort which does have a standard vswprintf() starting from
version 5.1 which we can use.
