Seems like in this case you are somehow not including the dos.h
header file, where REGS are declared.  Try to add it.

AFAIK, DJGPP doesn't have _doserrno.  As a first cut, try this:

	#include <errno.h>
	#define _doserrno  errno

and see what happens (_doserrno does not always equal errno, but it's
close; you can refine that later by calling DOS function 59h directly).
