Don't you think people will understand that?
Would a comment help?

"config.h" really is required in every .c file that's compiled
as part of a build.  If it's not, you're asking for build failures
whenever you encounter a compiler with e.g, insufficient "const" support.

This is an issue even with those simple example files,
since there are uses of "const" in libvirt.h, which is included
by each of those two.  On a build host with a deficient compiler,
the config.h-supplied definition of "const" is required in that case.
Each also includes stdio.h, which (with gnulib) requires
