well, you don't need much special knowledge (I hope).
You wrote the most of the macro for me.  Then I used the definitions
from the file /usr/share/autoconf/autoconf/headers.m4 as templates.
(This file can be found by grepping for AC_CHECK_HEADERS.)

I adapted your check.
Before I try to submit it, I'd like to ask you (or others on the
lists) to test it.

(Delete the AN_HEADER line there are problems with it.)

Thank you,
	Stepan Kasal
