Description:
------------
Able to compile up to and including php-5.2.2 without error 
(and run in a production environment. My attempt to build 
php-5.2.3RC1 dies in md5.c (An expression appears after a "return" in a 
"void" function).

Reproduce code:
---------------
IRIX64 Mai 6.5 6.5.30f 07202013 IP35

Reproduce code:
---------------
