[M3devel] Popup Windows stalling regression tests on WinXP

[Olaf Wagner]

Sorry, I currently have neither the time to install debuggers on my
slow VM machine nor to chase after such bugs. What I hoped is that
there is some system switch that turns off all such popups.
If there is not, there may not be much further progress from me for
some time. If I start a program like the compiler without any GUI
from the command line, I do not expect to get any popup boxes on
some unmonitored server machine. It will just not work this way.

Even if I found and fixed this special problem now, we'll run into
the next one some time later when the tests are hanging again...

PS: As for running only one test with the m3tests makefile, I simply
     switch off most of the definitions with `if "" ... end' and
     copy the interesting line just before.
