No *public domain* stuff is out there, but there are free-use utilities
available: 

The Austin Code Works sells source to Bison, Prep, and Charles Forsyth's
ancient version of Lex.

UNIX BISON source exists, and is available via ftp from prep;
a PC port under Microsoft C
4.0 is available with source from the PCSI BBS in New York (212-529-0498).
This port is SMALL MODEL -- 64K code, 64K data;  I fed it the C grammar
from the back of Harbison and Steele, first edition, which overtaxed its
space.  I haven't gotten BISON to work under large model with Turbo C...
(boy, have I tried...  I will have to beat on it some more :-)

Beta for another, much more ambitious LEX rewrite has just been made available
via ftp in UNIX source by vern@lbl-{csam,rtsh}.arpa -- he has MS-DOS diffs
available, but won't be answering mail until the 27th.
