favourite organization.
==========================================================================================================
Thank you to Microsoft for donating a copy of Visual C++ 6.0 to help
wxWidgets compile on this version of the compiler (for a Virginia Tech
course).
We do not refuse to list a program merely because it mentions
a non-free platforms on which it runs. I've explained that already.
I don't like the warm and positive attitude towards Microsoft
expressed by that thank-you. If wxwindows were a GNU package I would
ask the developers to change that.
But wxwindows is not a GNU package, and I doubt I have veryx much
credit with its developers. I'd rather not use it on this.
