Hi Philippe,

I don't know, frankly, since I have never had to use it. It was just the only
pocketpc gcc toolchain I found to be packaged for Debian. If you happen
to find out if it supports pthreads or doesn't, I'd love to know, too.

You'd have to ask that on a WinCE development mailing list :/

Note that you don't need pthreads for Kaffe in general, only if you
intend to use the AWT/Swing code. And if there are no pthreads for
WinCE, you could adapt GNU Classpath's native sync layer to Kaffe's
jthreads, which should let you execute the GUI code on jthreads as well.

cheers,
