[Project-managers] turn off windows popups in failing unit tests

[Ted Ralphs]

Hi Stefan,

This is implemented for SYMPHONY in both trunk and stable. I have built 
it successfully under Msys with gcc 4.2. MinGW helpfully includes its 
own implementation of the windows.h header file, which was successfully 
found during configuration, and the unit test built properly, but a 
window still popped up when I induced a seg fault. I'm not sure if this 
is supposed to work with MinGW or only with Visual C++. I can't test 
with Visual C++, since I don't have the SDK installed. Let me know what 
you find.

Cheers,

Ted
