Php 4.0.4pl worked fine. When upgrading to 4.0.5 I ran into this compile error. After I got this error i tried compiling 4.0.4pl1 and no problems. So I am suspecting it is has something to do w/ 4.0.5

CONFIG OPTIONS -
 ./configure  --with-apache=../../../apache_1.3.19 --enable-track-vars --disable-debug --with-mysql
