They actually do this checking because they are part of some standard macros.

You should ask yourself if you actually use this information anywhere.

I never check for header files that are usually part of the compiler or base system. The corner cases can often be easier handled in other ways than some strange checking in the build system.

And this is still one of the most annoying thing about autotools.
