Because byacc is indeed supported.  There aren't any special things
needed, it's not quite clear why Solaris' yacc stumbles across it.
It's probably just a minor implementation issue.  I also had to change
the <str> start condition in lexer.l to <strng>, as the name of the
start condition eventually ends up in a #define str 1 statement, and
apparently at least some versions of flex floating around (like the
binary package I found for Solaris 10) then try to use an internal
function like

YY_BUFFER yy_something (char *str) {
   do something with str here
}

The result doesn't look so good if str had been defined to 1...  My
FreeBSD version of flex doesn't do it (they use some internal symbol
that starts with yy_).  In that case, the reason was pretty obvious
though, and the fix was simple.

Perhaps by looking a bit closer, I can also see the reason of the
problem with Solaris' yacc.
