Paul,
Here's your culprit:
/* XXX This is from Win32's <windef.h> */
#ifndef APIENTRY
#if (_MSC_VER >= 800) || defined(_STDCALL_SUPPORTED)
#define APIENTRY __stdcall
#else
#define APIENTRY
#endif
#endif
This screws up a similar chunk of code in the standard Cygwin w32api
include files (which check for a slightly more liberal condition than
just the MSC version).
