Yes, there is.  The macro __DJGPP__ has the major version of DJGPP (i.e.,
2) as its value.  __DJGPP__ wasn't defined at all in DJGPP v1.x.

In general, to learn about any predefined macros, you can do one of these:

	1) look in the lib/specs file
	2) run gcc -dM -E foo.c (where foo.c is any empty file)
