There are several significant differences between the mingw32 (gcc 4.3.0 based) compiler and the GCC 4.4 and later compilers.
Mingw32 requires that types int, long, long long, unsigned { int, long, long long}, float, and double be the only types passed to va_arg(). This requires the programmer to ensure that va_arg is called with type int for arguments of any type with a size less-than or equal-to int. GCC 4.4 and later does not require this and performs the appropriate promotions for you.
Mingw32 uses 32-bit long in both ia32 and x64 mode. GCC 4.4 makes long a 64-bit value when in x64 mode.
