I don't think it is the autoconf way to check for *every* header file.
Some are just going to exist or we're in trouble, e.g. groff-getopt.h.
Some will always exist or we haven't got a C compiler, e.g. assert.h.
And some are implied by the presence of others, e.g. X11/IntrinsicP.h.

I think Werner just has to check for ones that can sometimes be missing
and put a workaround in for those cases.  That's not saying that some of
the above don't fall into that category.

Cheers,


Ralph.
