Don't know. Hoe to you find out without MSVC installed? Problem is I
lost my test machine as the problem went after installing MSVC 5.0 and
the owner isn't too happy to reinstall the entire system to make a bug

PlCon also includes <windows.h> for DDE and DLL handling.

Also promising might be that PlWin is multi-threaded, using the main
thread to run Prolog itself and a small helper to run the I/O window.

Anyone?  Both working and non-working setups are welcome?

Nice, though I prefer a computer that simply works :-)
