----- Original Message ----- 
I can't interpret Microsoft's license for Microsoft.  The language of
their license clearly is intended as an attack on the GPL; but it is

>From the GPL's perspective, it's permitted.

Another option, if you can afford to wait, is to use Trolltech's Qt
version 4 is released.  Version 4 will be licensed under the GPL for
platforms.  This will make your code more portable.
