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.
