Patches must have a comment at the beginning to explain what they do,
why, and what the upstream status is.

Please pay more attention to these rules before pushing.  In general, I
would recommend that you wait for some review before pushing.  (This is
sometimes slow, but hopefully others will help reduce latency,
hint hint! ;-))

It is best to avoid modifying .ac or .am files because that requires
adding a dependency on the autotools.

What problem does this patch solve?  I’m confident this can be worked
around without modifying the .ac file, for instance by passing the right
ac_cv_ variable as a ‘configure’ argument.

Thanks,
Ludo’.
