These problems should be addressed in:
    Help-flex mailing list
    help-flex@gnu.org
    http://mail.gnu.org/mailman/listinfo/help-flex


    help-bison@gnu.org http://mail.gnu.org/mailman/listinfo/help-bison
    bug-bison@gnu.org http://mail.gnu.org/mailman/listinfo/bug-bison


You may, however, be using old versions of Flex/Bison.

Bison, and also later versions of Flex I think, have changed to that
output source code files are generated from skeleton files via the
macro program M4. This makes it easy to write ones own new skeleton
files. If you think this is necessary, GNU might be happy if you
donate some code.
