I don't know if this is approriate, but it does sort-of wrap up the issue.
A definitely non-AT&T, non-FSF version of yacc was posted to the minix
newsgroup earlier this summer. I have self-compiled the parser, and it
seems to be about on a par (size, speed, etc.) with the AT&T and FSF
parser generators. The author mentioned that it runs rather slowly, but
with a reasonable disk cache, I don't see any significant difference in
speed (no more than perhaps 2-1), and the code is reputed to have run on
a Z80 system at one time!
