1997-07-30mickey has pieces he has not committed.flipk
if he puts the tree in an unbuildable state again.. anyway, all these problems came from the fact that etc/genassym.cf wasn't even being used, and assym.h is where key defines were supposed to be coming from. now we actually include etc/genassym.cf in the genassym.sh processing, and remove the #includes i had in place to work around it. now if mickey had committed machine/biosvar.h, etc/Makefile, and these asm files all at the same time, there wouldn't have been a problem....
