i found indeed a work-around, or better to say something that's even much more simple then i had.
so for now i'm alright with the tools i have for the PIII's.
it leaves open the cases of the compiling/building going wrong for Windows and/or without SSE2. if needed i'm perfectly willing to assist in testing solutions for that.
iohannes, when you think it's useful i could send you the dll, maybe you can see what's wrong with it.
