Zero sounds a little depressing ;)...

It's not zero. I helped a few persons to get a MSVC-based environment that can build octave.

Thanks for pointing out that it is so slow. Yes, I would like to compile the
64bit binary on 32bit OS. Why? For the challenge and for education. The more
errors occur the more I should learn.

To answer your previous question, the VCLibs archive I posted was the results of several years of spare-time development (creating my own toolchain and porting every single dependency to MSVC compiler). More recently, I integrated most of that work into MXE and at some point, it was possible to compile octave with MSVC using MXE, though I'm sure it's not the case anymore, I haven't look into it for a while. If you want to give it a try, use "./configure --host=msvc" when configuring MXE.

However, I should point out that all the work I did was targeted at 32-bits platform. If you want to target 64-bits platform, there are some core parts that you'll have to handle yourself, for instance the bridge between gfortran and MSVC.
