Subject:	Re: #if (DJGPP_VERSION == 2) ?

DJGPP V1 defines __MSDOS__ and __GO32__

DJGPP V2 defines those, and defines __DJGPP__ to 2 and __DJGPP_MINOR__
to 0

Use code like this:

#ifdef __MSDOS__
#ifdef __GO32__
#ifdef __DJGPP__
/* V2 */
#else
/* V1 */
#endif
#else
/* other ms-dos
#endif
#else
/* unix */
#endif


O_RDONLY is defined in both V1 and V2.
