The PHP development team finally released a new version of the 5.3.x release. I guess the issue we had in compiling 5.3.3 was not important enough to warrant an earlier release. I haven’t found any problem yet with this version but I must admit that I haven’t tried out all the possible variations yet, but will continue to try them all out.
The error we encounter is listed as solved anyway in the ChangeLog (52417 and 52413).
