Don't fret - I found it interesting.

I've been using GNU-Win32 for years; it's generally solid, and the CHM docs are nice, but there are some issues with it. But last time I was looking for a replacement, I couldn't find one! Gow looks like it might be just the ticket.

As for MinGW/MSYS, last I looked, MSYS looked a bit incomplete for my purposes. I don't have any interest in or need for the MinGW gcc and autoconf bits, which tools looked to be its main advantage over GNU-Win32.
