Hello bug-autoconf, The current test for the trace bug in autoconf/m4/m4.m4 does not reject IRIX 6.5 /bin/m4. The latter accepts unknown options starting in `--', outputs nothing for the bad trace, and exits zero.
This wouldn't itself be so bad, as `make' quickly unveils that GNU m4 is needed, but the test happens to claim that it actually found GNU m4. Cheers, Ralf
