This bug is similar to but not the same as Bug #19973.

Basically I did a 'configure' followed by 'make'. The make command terminated with: /usr/installs/php/php-4.3.0RC4/ext/zlib/zlib.c:48:
/usr/installs/php/php-4.3.0RC4/ext/standard/basic_functions.h:126: #error Need type which holds 32 bits

(There were some warnings reported by the compiler but they didn't seem important)

The same configure line works with php 4.2.3 on the same machine and the config.nice is as follows:

#! /bin/sh
#
# Created by configure
