Mixup?  211 vs 127?

Anyway, the failure of 211 is easy, and due to 'false' exiting 255 on
your system rather than 1 (which is documented in autoconf.texi).
Please confirm that the patch below fixes the issue; the test addition
is to ensure the respective code path for $srcdir != '.' is covered as
well.

Thanks,
Ralf

    config.status: consistent exit status with nonexistent config file input.
    
    * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Ensure we
    exit with status 1 rather than with that of 'false', for
    reproducibility.
    * tests/torture.at (Missing templates): Also test code path
    for $srcdir != '.'.
