One piece of bad news is that it doesn't work on Win3.X systems
(win32s). The PE-COFF object files that mingw32 makes simply won't
load, even for a "Hello, world" example.
The most likely candidate to get something running on that platform
(I, for one, still have quite a few students with older notebooks
and/or upgrade paranoia) seems to be RSXNT, but it's not all that
simple. It's also GCC-based, but the "specs" file is set up
differently from the mingw32/egcs one, which may create a great deal
RSXNT can (e.g.) be found at
I did a quick test and it does seem that a little fiddling makes it
possible to compile e.g. wincons.c with mingw32 headers plus a few
extra defines from the mingw32 specs file, so it would seem to be
doable, but it's hardly trivial. (Actually, this was with the ordinary
Linux GCC, but it's the header files that always cause trouble).
I also haven't got the foggiest about how to create DLL's with RSXNT,
especially how to to the important callbacks to the R binary (call_R).
And, there's no g77 in RSXNT, so you'd need f2c. Perhaps it would be
easier to make the egcs cross-platform tools once and for all?
In any case, we need to do an "official" collection of tools. I tried
to compile using Guido's files during Easter, but immediately got
stopped by the absence of an "ls" command...
