Description:
------------
make fails when attempted (with oci8 enabled) against Oracle 8i libraries.


Reproduce code:
---------------
./configure --prefix=/usr/local/php5 --with-oracle=/data/oracle/oracle8i/app/oracle/product/8i --with-oci8=/data/oracle/oracle8i/app/oracle/product/8i --with-xml --with-apxs2=/data//apache_2.2.4/bin/apxs --with-openssl=/usr/local/ssl --with-ldap=/usr/local/openldap --with-mysql=/usr/local/mysql5 --enable-sockets --with-imap=../imap-2004g --with-mysqli=/usr/local/mysql5/bin/mysql_config

Expected result:
----------------
successful make ..

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

see http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2007-May/120308.html for example of it being fixed ...
see
http://bugs.php.net/41348 for an unhelpful suggestion on how to solve it (that was against 5.2.2, I've hit the same in 5.2.3).  I *cannot* just upgrade Oracle on this box to get php to compile.
