I finally succumbed to persistent pressure to have a look at WinBoard 4.0.2 for JFW, to fix the broken ICS support. It seems I have succeeded in doing this. I still want to apply a patch to make it speak the thinking output in a useful way, when showThinking
is on (e.g. in analysis mode).

My question now is this:

The version I downloaded from Tim's website (source package) went accompanied by a file jfwapi32.dll. It was not clear to me where this file came from, and what its license situation is. there was no source code for this file, so I suppose it is not GPL'd. I could not find anything about it in the copyright notice included in the package.

When we are going to distribute my fixed version, would it be allowed to redistribute
this jfwapi32.dll with it?

I'm not a GPL expert, but I think if you explicitly link with the DLL, then it must be open source. Maybe it's safe to link at runtime using LoadLibrary() and GetProcAddress() to access the API calls, particularly since it is just providing extra accessibility features not needed for winboard to function.

In any event, I'm not in favor of shipping that DLL. People running the JAWS software would already have it, so nobody else needs it.
