Actually, it doesn't. This method breaks as soon as size_t != u_long and
might only work in a few edge cases like the size_t being the last
argument and the byte order is Little Endian. This is worse because IIRC
Microsoft decided to use IL32LLP64 or something similarly fancy.
A more portable approach with autoconf can be found in pkg_install, look
for MISSING_SIZE_T_SUPPORT and the corresponding AC_CHECK_SIZEOF calls
