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.
