Which version of the C++ source code did you use for this?  The
"official" releases before 0.7.0 were all built with VS 2003 and AFAIR
didn't even build with newer version of VS.

Have you tried to compile the DLL from the 0.7.0 source code using VS
2008?  I'm asking because I'm beginning to suspect that (my
installation of) VS 2005 is the culprit.  I've tried with Michael
Goffioul's VS 2005 version of 0.5.0 and with Matthew D Swank's VS 2005
version of 0.6.0 and both failed as well.

Strange...
