Description:
------------
Attempting to build php with the php-fpm SAPI fails on AIX 6.1. It's clearly 
because the processor type isn't defined in php-5.3.5/sapi/fpm/fpm/fpm_atomic.h.

I have no idea what the appropriate typedefs for this architecture should be.

Additionally, I'm compiling with the IBM xlc compiler.

I can successfully compile every other part of PHP with my toolchain.

Output of uname -pM:

powerpc IBM,8203-E4A

(This is arch and machine model number - an IBM Power 520 Express)

PHP's configure line:

./configure \
    --cache-file=../config.cache \
    --prefix=/opt/freeware \
    --with-config-file-path=/opt/freeware/etc \
    --enable-shared --enable-static \
    --without-pear \
    --with-gd=/opt/freeware \
    --with-openssl=/opt/freeware \

    --with-bz2 \

    --with-iconv \
    --enable-dom \
    --enable-json \
    --with-pcre-regex=/opt/freeware \
    --enable-fpm
