Hmm, just grep for NULL in djgpp/include. Probably stdlib.h is a good
choice. Look at the info for libc's malloc; it probably says there
which header file you'll need. I'm not on my DJGPP system now, so I
can't be exact.

As for changes between 2.7.2.1 and 2.8.1, I don't know but the
CHANGELOG and perhaps other readme files in the sources can tell you?
Anyone else have an idea?

I don't know how that debugger looks, but you could try fsdb, edebug32
and rhide and see if those suit you better.

Link to any tutorials for gdb? Have you read the info pages?
