Shut the complaints about POSIX incompatibility by passing -Wno-yacc to
bison. An alternative would be to not pass -y, but that caused seemingly
unsolveable problems with automake and expected file names.
Fix two warnings about deprecated '%pure-parser' and '%error-verbose'
statements by replacing them with what bison suggests.
A third warning sadly left in place: Replacing '%name-prefix' by what
is suggested leads to compilation errors.
