    I suggest testing for string.h/index and if this fails for
    strings.h/index...

    something like this:

    AC_MSG_CHECKING([for string.h containing index])
    AC_TRY_COMPILE([
    #include <string.h>
    ],[char a[] = "a";
    int c = index(" ", ' ') - a;],
    ac_need_strings_h="no";
    [AC_MSG_RESULT([yes])],
    ac_need_strings_h="yes";
    [AC_MSG_RESULT([no])])

    if test "$ac_need_strings_h" = "yes" ; then

    AC_MSG_CHECKING([for strings.h containing index])
    AC_TRY_COMPILE([
    #include <strings.h>
    ],[char a[] = "a";
    int c = index(" ", ' ') - a;],
    CPPFLAGS="${CPPFLAGS} -DNEED_STRINGS_H";
    [AC_MSG_RESULT([yes])],
    [AC_MSG_ERROR([index () is neither in string.h nor in strings.h])])
