Hello,

I was not able to find gcc 3.4.4 for the latest Cygwin nor could I find 
Cygwin 5.1, so I switched to trying the MingW route. They have a gcc 
3.4.5 compiler which I chose. Ultimate I ran into undeclared symbols, 
when running mwm.

Here's what I did:
1) MingW installer: 
http://sourceforge.net/projects/mingw/files/latest/download and installed
1.a) added gcc 2.4.5
2) CMake 2.8.8 installer: 
http://www.cmake.org/files/v2.8/cmake-2.8.8-win32-x86.exe and installed
3) Follow vm build instructions: 
http://www.mirandabanda.org/cogblog/compiling-the-vm
3.a) checkout Cog sources
3.b) Change directory to build.win32x86
3.c) edit plugins.ext to remove Bochs plugin
3.d) run mvm

I received errors, listed below. I am not sure what the next step should be.

regards,
Henry
