   We are dealing with Microsoft Windows and most likely Microsoft
   Visual C (MSVC).  (Heaven help us.)  Sadly, MSVC does not correctly
   define some of the standard types specified in ISO/IEC 9899:1999.
   In particular, it does not define the "long long" and "unsigned long
   long" types.  So, we work around this problem by using the "INT64"
   and "UINT64" types that are defined in the header file "windows.h".
