Hi, Peter!

I'm not an AT&T assembly guru, but I'll help you =3D)
Few days ago I fixed Allegro lib (after reading the answers to my=20
question from listserv, thanks to guys who posted 'em - Weston T. Pan and=
=20
Ove K=E5ven).

In this particular case you have to change lines 227 and 244 from=20
'incl %ah' to 'incb %ah'. Simply AS from DJGPP 2.01 is more strict with=20
argument sizing, and ah is a byte reg, not double word. In general, if=20
you will meet similar errors, try to use -E option to get preprocessed=20
source, and then analyze it.
