It's a harmless issue, due to what seems to be a bug in that old version
of Xrandr.h (which is in any case too old for Emacs to use it).

This seems to fix it.
I do not know if it is appropriate for emacs-24?

That message about "present but cannot be compiled" is emitted by old 
versions of Autoconf; newer ones don't bother.  As this does not appear 
to be a bug in Emacs I'm taking the liberty of closing the report.

It is still produced by autoconf 2.69, which is the latest release of
autoconf AFAIK. Which versions are you talking about?

I don't remember, but I see that you are right and 2.69 still produces the 
messages.  The master (post-2.69) version of Autoconf stopped producing these 
messages about a year ago; perhaps I was using something later than 2.69.
