   [problems using "bison -y" instead of "yacc" when building perl]

This is indeed a minor incompatibility between bison and yacc.  yacc puts
a line of this form in "y.tab.h" which bison does not:

    extern YYSTYPE yylval;

The most portable solution to this that I can see is to add this
declaration to each of the files which include the ".h" file generated by
yacc:

    cons.c perly.c str.c toke.c
