So there is the possibility of insisting on a new enough yacc at
configure time, and forcing bison as a dependency for solaris.  This is
a tough call, having to separate what's behind vs. what's normal.

Alternatively, posix says that yacc must support -b for prefix, so that
could be used instead.  If Solaris doesn't conform to posix, I am
relatively unsympathetic and making Solaris people install bison seems
ok :-)
