I am still working to port the 5.08 SConstruct for Windows to Microsoft Visual C++ (MSVC) instead of MinGW/MSys. 

As I mentioned before, I am doing this because the version of the MinGW/MSys toolchain that builds Csound is getting quite old, and newer versions of that toolchain do NOT build Csound with everything that goes into the Windows installer.

I am working on this every evening, and it is proceeding apace. No show-stoppers yet. However, there is considerably more work than I had anticipated, because the SWIG step for the various interfaces is much less forgiving with MSVC than it was with the MinGW/MSys toolchain. Also, the MSVS system is less Unix-like (no dirent.h, for example) and that will require changes or workarounds in some code.

Once I get everything building, enough has changed that there may be  considerable debugging required.

I expect that getting a working Windows installer built with MSVC could take another 1-3 weeks. 

I continue to feel that moving to MSVC will probably turn out to be a very desirable step. Microsoft still seems committed to giving away their high-quality compiler, editor, and debugger. The only pre-requisite library that does not now come with a Visual Studio build system is liblo. Ordinary Windows programmers with MSVC will find Csound with MSVC libraries much easier to program to. In particular they will not need to make their own import libraries, and will be able to link with all of Csound's C++ interfaces. All of the C interfaces in DLLS and the C++ interface in csound.hpp will continue to be usable without change from MinGW.

The main unanswered question in my mind is performance. Which runs faster -- MSVC or MinGW? I am guessing they are pretty close. We will see. If MinGW turns out to be considerably faster I will revisit the MinGW/MSys toolchain.

Regards,
Mike

Will the dll produced by MSVC work with mingw, either by linking 
directly or using pexports and creating an import lib?

I agree.
