Quite some time later it does appear that the problem or a 
problem similar to this still exists, at least with the make
utility :( 

I had a user report the exact same error message when using 
the Zeus for Windows IDE to run the Gnu make utility. A quick 
search of google shows that other programs have come across 
the same error condition.

After some investigation, it looks like the bug also relates 
to the cmd.exe interpreter. In fact if the command.com is used 
then the problem goes away.

For any one that might be interested, more details on the bug 
and the resulting workaround can be found at the following 
forum topic:
