Wine on Windows is an idea of real-world usefulness, as newer versions of Microsoft Windows increasingly fail to support apps Wine still supports.
I've started a wiki page: http://wiki.winehq.org/WineOnWindows
This covers my experiments with the three main POSIX layers (Cygwin, MinGW and Interix) on XPsp3.
Various people have told me they've got it to work before (native compilation and install on Windows), but I seem to be the one gathering data :-) If anyone who's done it could please (a) put there what they did with what versions of Wine and tools (b) check with current Wine, that would be most appreciated.
