You do need to use the latest cvs version for 64 bit builds.

You may find that using the VC build works with your application. The 
VCE version has problems anyway and is not really recommended.

This problem has been reported to me by Daniel Richard G. who has also 
provided a substantial patch that also includes a large number of other 
changes not necessarily related to this issue. Unfortunately I just 
don't have the time now or the [64 bit MSVS] tools to properly 
incorporate and test complex patch sets or coordinate those who do, 
considering that this project aims to work with several compilers (e.g. 
MS and GNU) and their various versions and supported architectures.

But I do want to note here that the current code in cvs has been built 
and well tested on several 64 bit systems and compilers, but presumably 
not using this specific MSVC++ compiler version.

I don't know if this link helps at all with the cast error, i.e. adding 
the /DNO_STRICT compiler option to the compiler flags in the nmake Makefile:
