Ralf Becker 232252475f patch fixing many depricated functions (eg. posix regular expressions) and features, which fill up the error_log under php5.3 (and will no longer be available under php6).
Patch is mostly created by script in egroupware/doc/fix_depricated.php in separate commit.
I do NOT advice to apply this patch to a production system (it's commited to trunk!), as the automatic modified regular expressions have a good change to break something ...
