undefined symbol ap_casecmpstr error while enabling mod_cern_meta module

Hello,

We have downloaded the *mod_cern_meta* module from svn, few months back and
it got worked with Apache version 2.4.

When we try to download the same module from svn again and try to enable
the module, we received the following error.

====
undefined symbol: ap_casecmpstr
====

As a temporary fix, we have edited the below lines on *mod_cern_meta.c*
from the old file which we have on different machine.

====

From:
if (!ap_casecmpstr(w, "Content-type")) {

To:

 if (!strcasecmp(w, "Content-type")) {

From:

else if (!ap_casecmpstr(w, "Status")) {

To:
else if (!strcasecmp(w, "Status")) {
====

Could you please review the recent changes on svn on this file and let us
know whether any modification that we can do from our end to get rid of
this error.

Thanks,
Rajesh
