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
