When someone makes a commit to configure.ac, the configure file has to
be regenerated. Usually automake adds rules so that if configure.ac is
newer than configure, it runs autoconf again. We can try to add some
rules like that to the toplevel Makefile, but I'd like to take a look at
the way automake does it before adding some half baked hack.

However, the takeaway is that if you're seeing build errors, you'll want
to check that configure is up to date and that it's been run again.

Here's a handy trick for regenerating the autotools and keeping your
configure arguments:

$ autoreconf -iv && ./config.status --recheck && ./config.status

That's pretty much a surefire way to ensure the autotools (whichever
ones) are refreshed, and the second part runs configure again with your
arguments you used before.
