Possibly a bug in the section that defines the types that are used in
that file.  If you look at the top of the file, you will find this:

----------------------------------------------------------------------
# include <windows.h>
# ifndef __CYGWIN32__
#  include <wtypes.h>
   typedef          _int8  Tsint8;
   typedef unsigned _int8  Tuint8;
   typedef          _int16 Tsint16;
   typedef unsigned _int16 Tuint16;
   typedef          _int32 Tsint32;
   typedef unsigned _int32 Tuint32;
   typedef          _int64 Tsint64;
   typedef unsigned _int64 Tuint64;
# endif
----------------------------------------------------------------------

Can you move the "# endif" line up so it is just after the
"# include <wtypes.h>" line and tell me if it works?
