Status:

Bugs caushing Csound GUIs to crash on exit appear to be fixed.

Everything but OSC and csoundvst~ builds on MSVC 2008.

Everything but csoundvst~ and the PortMidi module builds on MinGW with GCC 
4.2.1.

Python works, GUIs work. Still need to test CsoundVST, Lua, Lisp, Java.

Windows installers are fixed (I think -- needs feedback, but not uploaded 
yet).

Very approximate performance comparison:

Trapped in Convert rendering to a soundfile:

COMPILER         OPTIMIZATIONS          SPEED
GCC 4.2.1        -03 mtune=prescott     7.9 seconds
MSVC 2008        /O2 /fp:fast           6.8 seconds

The rendering speed with GCC 4.2.1 is significantly faster than any Windows 
build of the past. The rendering speed with MSVC 2008, in turn, is 
significantly faster than GCC 4.2.1.

I will try to run the OSC opcodes built with MinGW in the Csound built with 
MSVC. If that works, I will release the MSVC build. If that does not work, I 
will release the MinGW build because it contains the OSC opcodes.

I also may try some alternative optimizations on the MinGW build.

Regards,
Mike
