[PATCH 0/5] Configuration cleanup and warning fixes

[Alan Coopersmith]

Started cleaning up some of our libc fallback function checks in configure
and the more I cleaned the more layers of crud I found underneath.

Also silences some annoying warning noise from gcc, and two warnings
from the Sun compiler that the recent changes to xorg-macros had promoted
to errors, causing builds to fail with that compiler.

This does export the HAVE_FFS, HAVE_STRNDUP, etc. definitions to drivers,
but if you built the Xserver with a libc that had those, and then build
the drivers with a less capable libc, you're going to have problems anyway,
and this should solve some reported problems with conflicts between our
strndup definition and gcc magic for it.

Alan Coopersmith (5):
  Remove unused function checks from configure.ac & include/*.h.in
  Move to autoconf standard function name checks & defines
  Fix gcc warnings about redundant declarations of fallback functions
  LoaderOpen returns either a valid pointer or NULL, so don't check for
    < 0
  Add dummy return 0 to Xnest & Xephyr io error handler for Sun
    compilers
