This is part of the package itself.  I won't test for its existence.

autoconf already defines a macro to test for the presence of libraries
and header files of X.  I'm relying on that and won't add new tests
except there is some trouble.

The current policy is to add a test only if there is a failure on a
particular system.  Today, there are many standards like POSIX which
define a lot of header files, and most operating systems follow it.
Older platforms are dying so I really don't see a reason to blow up
the configure script with those tests.
