[CMake] CMake/MinGW/Windows XP 32-bit: command line arguments delimited by semicolon?

Hi list,

Found some odd behaviour while setting up CMake on Windows XP. I've
tried to correct the word-wrapping cmd.exe does, not always
successfully; I hope you can read this:

It's the line beginning cc1plus.exe that confuses me. Why are the
command line arguments separated by semicolons? It should be spaces.
I've looked in the generated Makefile and CMakeCache.txt but I can't
figure it out. This MinGW installation has been installed and working
for a little while now, so I don't think it's a MinGW problem.
