Well, generally you don't need any include files to check for a function's
presence in a lib. The basic autoconf macros thus don't allow any particular
include files to be set for a specific function-in-lib check. We need to write
our own.

Perhaps something similar to this (should only be made if gethostbyname
wasn't already found, but let's ignore that for now):

AC_MSG_CHECKING([for gethostbyname in ws2_32])
AC_TRY_LINK([#include <winsock2.h>],
            [gethostbyname();],
            AC_MSG_RESULT(yes)
            AC_DEFINE(HAVE_GETHOSTBYNAME, 1, [If you have gethostbyname])
            LIBS="$LIBS -lws2_32"
            ,
            AC_MSG_RESULT(no)
           )
