Hmm...this is interesting:

/usr/src/devel/kernel/src/winsup/cygwin/external.cc: In function 'long
unsigned int cygwin_internal(cygwin_getinfo_types, ...)':
/usr/src/devel/kernel/src/winsup/cygwin/external.cc:413: error: 'bool'
is promoted to 'int' when passed through '...'
/usr/src/devel/kernel/src/winsup/cygwin/external.cc:413: note: (so you
should pass 'int' not 'bool' to 'va_arg')
/usr/src/devel/kernel/src/winsup/cygwin/external.cc:413: note: if this
code is reached, the program will abort

This didn't happen with BOOL, because it is typedef int, anyway:

windef.h:

typedef unsigned long DWORD;
typedef int WINBOOL,*PWINBOOL,*LPWINBOOL;
/* FIXME: Is there a good solution to this? */
#ifndef XFree86Server
#ifndef __OBJC__
typedef WINBOOL BOOL;
#else
#define BOOL WINBOOL
#endif
typedef unsigned char BYTE;
#endif /* ndef XFree86Server */

So, to avoid requiring #include <windows.h>, I guess the next best thing
is option #3, right?
