I have also downloaded mingw32 recently (for one of my projects) and also
didn't get any further :-).

Is mingw32 stable enough, anyway?

I know how to work with mixture of MFC code and that of PDC Prolog (former
Turbo Prolog), which resembles Mercury for static typing and intention to
compilation. (BTW its current development team resides in St.Petersburg,
my native town :-)).
But PDC Prolog looks 100 times simpler (more naive?) than Mercury.
And compatibility with Microsoft C's is well built in.

If I knew Mercury better I would to try to do something like this with Mercury.
Probably after some learning and playing with under Unix...

There is theoretically a possibility to port MFC to gnu C++. There is a
"migration kit" (???). Some people reported that port is already done.
But g++ is not well suited to work with large
C++ libraries, esp. under slow file systems like fat and ntfs.
I have experience with TurboVision. (While compiling its headers,
the nt virtual dos machine, containing djgpp, grew up to 13M  -- and 7M
under Linux).

As an example: Python scripting language, originated from 
Unix environment, has quite "native" port to Win32 under Visual C
It is very useful. There is no "official" version of Python for gnu-win32 or
Also Tcl.

As I conclude seeing the mailing list, 
for the current stage of language development it
is not very appropriate to complicate things with ports to Mac, Win32 etc.
I understand and agree. Unix is quite enough to make the language itself stable.
