This is almost certainly perfectly fine, and I haven't looked at context,
but I wanted to make sure that someone had noticed it:

I believe the renaming of configure.in to configure.ac is specific to
Autoconf. Cygnus configure is a different (and older) beast; if anyone is
actually still using Cygnus configure, those files would still be named
configure.in, not configure.ac.
