Hi,

I have now tried to write a simple test for the framework which was a 
litte more difficult than I thought first. Anyway, I have uploaded the 
patch against 2.6.3 on the bug report page.

I could not figure out exactly how to include a cross-compiling test in 
the Tests/CMakeLists.txt file in a clever and nice way, such that it 
finds out if automatically if Visual Studio 2005 and/or 2008 is 
installed or neither. Thus my test hack is really ugly although I tried 
to get it somewhat nicer for a few days now - if someone could rewrite 
it in a nice fashion I'd be really glad.

First a cache file is copied to the build folder. First I thought 
setting the correct CMAKE_GENERATOR in the Cache file should be 
sufficient, but whatever I did configuring the project failed. Thus I 
think the --build-generator flag must be provided to make it work, which 
makes everything more complicated (finding out what compiler is 
installed!?). Because I could not find a workaround to this, I simply 
assume VS 2008 to be installed and I hardcoded --build-generator to 
"Visual Studio 9 2008 (with SDK support)".  This means running the test 
only works if 2008 is installed. It simply creates a PPC 2003 sample 
project and compiles it in Release and Debug, which worked out fine for 
me. There is currently only the possibility to build, because executing 
and testing would involve interfacing the simulator which I guess is far 
too tough to be included here.

I'm open for any suggestions and comments to improve the current state 
to something which is really useable.

Clemens
