Cool.  Post back if you have questions on that part.  If you haven't
got better links, there's a draft on the fedoraproject.org wiki for
building packages:

http://fedoraproject.org/wiki/Docs/Drafts/BuildingPackagesGuide

I can't say I've followed it to learn to package (since it was created
long after I'd struggled to learn to build rpms :), but it does seem
to cover many of the things you'll need to know.

I looked harder and this is definitely an autoconf test.  The purpose
it to determine whether the preprocessor can detect missing headers.
You can find it in /usr/share/autoconf/autoconf/c.m4:

  # OK, works on sane cases.  Now check whether nonexistent headers
  # can be detected and how.
  _AC_PREPROC_IFELSE([AC_LANG_SOURCE([[@%:@include <ac_nonexistent.h>]])],
                     [# Broken: success on invalid input.
continue],
                     [# Passes both tests.
ac_preproc_ok=:

No need to really worry about it.  If it shows up in the configure
output, perhaps that could be fixed in the upstream configure.ac (or
configure.in), but it's not an error that should affect the build
AFAICT.
