No, you don't need to setup a vm. I managed to call various php 
versions, httpd servers, and mysql versions on the same OS (Win2000).
In fact every single supported version. Just IIS not yet.

The problem is that we cannot wait for this php bug to be fixed, similar 
to the pending mysql bug (> 4.1.x and 5.0.x: search fails BINARY pagename).
We rather must find a workaround for the affected versions.

The new unittest setup runs very fast now, so it's easy to test the 
complete SetupWiki and DumpHtml cycle.

It tells me that the bug comes only with the SQL backends.
The unittest uses the file backend, which runs fine (besides some 
remaining minor wikilens and references problems).
So we have to rewrite the unittests to test more backends.
