Description:
------------
Trying to compile PHP 5.01 with Apache 1.3.31 and Informix SDK 2.40 rpm and mysql 4.0.21.

I am running the following configure script:-

./configure --with-mysql=/usr/local/mysql --with-informix=/opt/informix --with-memory-limit --with-apache=../apache_1.3.31 --with-gd --with-zlib --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib

The above configure works fine with no error messages reported, however when running make I get an error message make: *** [sapi/cli/php] Error 1, and at this point it bombs out.


Reproduce code:
---------------
./configure --with-mysql=/usr/local/mysql --with-informix=/opt/informix --with-memory-limit --with-apache=../apache_1.3.31 --with-gd --with-zlib --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib


Actual result:
