Description:
------------
When building php against apxs2 (Apache 2.2.3) on Mac OS X (10.4.7) the make failes. It works fine when --enable-versioning is left out.

Reproduce code:
---------------
./configure --with-apxs2=/usr/local/apache2/bin/apxs --prefix=/usr/local --enable-versioning

Expected result:
----------------
All compiled

Actual result:
--------------
