Hello,
the text below seems to relly be a bug report with a proposed fix.
So I take the liberty to forward it to the bug report address.

This applies to the default test when calling
AC_CHECK_HEADERS([resolv.h])
Workaround is to use s.th. like this in configure.ac:
AC_CHECK_HEADERS([arpa/nameser.h netinet/in.h sys/socket.h sys/types.h])
AC_CHECK_HEADERS([resolv.h], [], [],
[[#if HAVE_SYS_TYPES_H
# include <sys/types.h>
#endif
#ifdef HAVE_NETINET_IN_H
# include <netinet/in.h> /* inet_ functions / structs */
#endif
#ifdef HAVE_ARPA_NAMESER_H
# include <arpa/nameser.h> /* DNS HEADER struct */
#endif
#ifdef HAVE_SYS_SOCKET_H
# include <sys/socket.h> /* DNS HEADER struct */
#endif
]])
Anyway, there should be a macro which provides this functionity.
