Or maybe we could get rid of ylwrap and assume yacc/lex support the
'-o' option.  After all:

  - the yacc- and lex-generated files are automatically distributed,
    so only the maintainers should be expected to regenerate them;

  - the sytem yacc on OpenBSD and NetBSD (not surre yet about FreeBSD,
    will check) support the '-o' option as well; and their lex too,
    since its flex

  - supporting proprietary yacc and lex should be low-priority IMHO.

Might this be something to consider for Automake 1.13?

Regards,
  Stefano
