Not sure I'm correct person  to start discussions over the of GPL, I think I'm not qualified.

I do know there is a plenty of established open source projects that use MFC, including GPLv2, such as different incarnations of
Tortoise (SVN,CVS, BZR, HG).

>From my point of view,  it is just a  system library. It came bundled with compiler, just like other library CRT which is non-GPL
that we use extensively for quite important functionality like strcpy() or say fopen().  Maybe this explanation will satisfy GPL
purists. I do not think CRT , MFC , ATL (libraries that come bundled with Visual Studio) have any written license, at least I have
never seen one. The source code is available, and installed together with Visual Studio.  If  one needs to redistribute one of this
libraries  as DLLs, there is Microsoft EULA that basically allows inclusion into any software . But we do not even do that, as we
link Visual Studio libraries (CRT, and also MFC now) statically, MySQL-ish way.
