configure.in problem with byacc and flex
fix the problem - can be applied now :)
configure.in file wrongly handles YACC and LEX variables so ./configure
exit succesfully, but make fails.
The problems are:
* it enables configuration even if no yacc is installed (it is necessary
for make) - YACC is set to byacc in this case
* the configure.in enables configuration if no lex is installed (it is
again necessary for succesfull make) - in this case YAC is set to ":" i
