HTTP_RAW_POST_DATA / Content-type

Hello, I'm running into a problem accessing $HTTP_RAW_POST_DATA in my scripts. I am interfacing with an external system that is doing a HTTP POST to my php script (I'm running 4.0.6). The variable $HTTP_RAW_POST_DATA is always blank even though the external system is sending me data. The problem is that the external system is not passing me a Content-type; they are including Content-length and the various other headers, but not Content-type. There is a known bug for this (http://bugs.php.net/bug.php?id=12208), and it seems that it is resolved in 4.0.7. Does anyone know of a patch for 4.0.6 that would resolve this bug? I wouldn't mind re-compiling 4.0.6 after patching the code, but I would rather not install 4.0.7 since it is still in the release candidate stage and the server in question is a production server. Thanks, Ryan
