Re: gnustep on cygwin

[Riccardo Mottola]

Hi,

I was never able to run stuff on cygwin. Another user reported some 
success here on the list months/years ago, but I wasn't able to share 
his luck and he did not tell us how he fixed things.

GNUstep still supports both, libffi being preferred. I use ffcall on mingw.

It shouldn't be necessary for any gcc >= 3 (except for some broken 
versions). It should compile though.

Mingw is a different beast, but indeed cygwin makes porting to windows a 
lot, lot easier. Actually, most things now work on mingw too, but of 
course X11 and unix sockets remain a big plus for cygwin.
