[PD] pd-ext.04 libraries don't load on xp!

[Martin Peach]

Just trying things at random, dlls in extra/cyclone and other folders seem 
to load with no problem. Zexy is weird because many of the objects exist as 
both dlls and abstractions with the same name, like a2l.dll and a2l.pd. The 
abstractions load OK but not the dlls, even [0x3c0x7e] loads OK, while 0x2e 
doesn't because it only exists as a dll.
