I know this problem, it is not related to PGCC. There's some inline
assembly in fsdb which contains mentioned instruction (xorl %al, %al).
You have to correct it to xorb %al, %al, it should work fine then.

BTW: Did someone succeeded rebuilding sources of libc & related stuff
(everything in djgpp/src subdir) ? I tried it before (djgpp 2.01, all
original files, gcc 2.7.2.1, binutils 2.7, no changes made to sources,
ran makeall.bat (hope the name is correct) in djgpp/src) and:
	I could not build fsdb without a change mentioned above
	I could not build math library (problem which someone posted
before, I think file(s) are *_finite.S, or so. Fix is quite simple,
again as in fsdb
	finally, ar produced VERY incomplete libc.a (overwriting my old
working one from distribution :-() and I wasn't able to fix this by hand
(I got lost in the phase of making stub000x which I didn't understood).
I believe that all those problems are caused by binutils 2.7, e.g. with
binutils 2.6 there would be no problem, although I didn't try it.

I think that it would be nice to update library sources to be compilable
without errors by current djgpp distribution.

thanx
Pavel
