  I'd like to port (and post) the 3/88 versions of c++decl and cdecl to MINIX.

  Since MINIX lacks both Lex and Yacc, the only way it could be portable is
to include the output files of Lex and Yacc.

  So, here's the question in hope there is some definitive answer:

  Can the output of an AT&T derived Lex and Yacc (mine would be Ultrix's [DEC's
flavor]) be freely distributed? That is, are the restrictions imposed
applicable only to the AT&T derived source code of Lex and Yacc, but not to
the output files produced by the tools?

  I think the output files are freely distributable, much as programs produced
with the aid of Turbo Pascal and Microsoft C are freely distributable (given
some minor conditions in their shrink-wrap license). If this is not the case,
would someone kindly explain why? If it is the case, are there some conditions
to be met so the output files are distributable?
