Hi Mark,

Glad that you found a way to compile your piece of software.

Well, yes it is :)  Now the question is what exactly do you
call Yacc.

byacc is not the "original" yacc.  It even turns out that
Bison and Byacc have a common ancestor, but it is not the
original Yacc.

Here, in some way your build process depends on specific
details of Byacc, which probably explains why it fails
with Bison.

But I'm glad that it works now!
