I'm having trouble building perl using bison.  If I run Configure and
specify bison as the parser generator, then Make uses the wrong set of
filenames to generate a parser.  I added a -y flag to the Yacc command
when $(YACC) = bison, so that it uses the yacc format names.  But then
I get an error when trying to compiler the scanner....  There must be
another bison incompatibility, because when I switched back to yacc.
I got everything to build. 

Does any one know what's going on?  I thought this was supposed to
work out of the box...  Below is a list of the errors I
get trying to compile the scanner

Expect 25 shift/reduce errors...
bison -dy perl.y
perl.y contains 25 shift/reduce conflicts.
