AC_CHECK_HEADER and AC_CHECK_HEADERS aren't designed for this
situation -- they are used when you simply need to know if it's
available so you can #ifdef HAVE_PACKAGE_HEADER_H.  You want to ensure
they're available by modifying some *CPPFLAGS variable if
package/header.h is not found with the default includes.

You will probably find bliss down the road of AC_COMPILE_IFELSE in a
loop that tries first with no additional -I, then with each of a list
of possible include directories, and adds the resulting -I directive
to a *CPPFLAGS variable while still respecting any user CPPFLAGS.
