Yes, that is the problem. When Florian had merged the SIMD intriniscs
branch those types were enabled, but they weren't ready yet. Thus he
disabled them later on again (a day or two later). If you had compiled
trunk during that time you can get mixed results, though it's strange that
it does...
If clean doesn't help (maybe even use the "svn cleanup" or whatever) you
could try to increase the PPULongVersion in compiler/ppu.pas, rebuild, then
lower it again and rebuild again.

Sven
