compile error on aix 5.3

hi,

trying to compile php 5.2.5 on aix 5.3 using the IBM C compiler. I am trying
to build php with the oracle client support. The oracle version is 10.2.0

here is the last part of the message when running make.

        /bin/sh /nfshome/richala/php-5.2.5/libtool --silent
--preserve-dup-deps --mode=compile /usr/vac/bin/xlc  -Iext/oci8/

make: 1254-004 The error code from the last command is 1.


any ideas why there is a syntax error?
