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

[Laszlo Ladanyi]

If you use CoinUtils the there is no need now to change your configure.ac.

I put what Stefan has suggested into CoinUtils (trunk only). Just include 
CoinError.hpp in your source file containing main() and on the top of main() 
invoke the WindowsErrorPopupBlocker(); function.

On non-windows environment it works fine :-). Could someone test it on windows 
with and without the SDK?

Thanks,
--Laci
