My understanding of the way copyrights etc. works, is that if someone
(besides us here at Tech) converts 'stacc' to C and posts it, he's in big
trouble.

For those who don't know, stacc is STill Another Compiler Compiler, which
is similar to Yacc, but produces a recursive descent parser (in any of
Ratfor, C, Pascal, PL/1, or Plp).  It is written in itself, using
ratfor. I should mention that Prime Fortran allows recursive subroutines
and functions or else it wouldn't work.  The ratfor used at Georgia Tech
on primes is NOT compatible with Unix Ratfor, either...

One of our very far back on the burner projects is to rewrite stacc in
C, and possibly post it (depending on if the lawyers would let us).

There are one or two other programs that have been rewritten in C from
the Georgia Tech Software Tools Subsystem, including the 'se' screen
editor.  I hope to post these, eventually, if and only iff the lawyers will
let me.
