The error message here about bison.simple is misleading.
It occurs when yyparse() fails but errorcount == 0.
In this case the reason that yyparse() is failing probably
has something to do with the "cc1: tmp-dum.c: invalid argument"
error messages, rather than the version of Bison being out of date.
