[M3devel] next problem (NT386GNU)

[Jay]

(I never used Windows 2000 much, but NT 4 worked solidly for a long time (didn't use CVS on it), hard to imagine Windows 2000 regressed much. XP and 2003 are solid, Vista I think is holding up in /this area/. There is the whole IPv4 vs. IPv6 transition still ongoing around the world.
I really think Windows is better than its given credit for. Not Win9x, but NT.
The Apple BS about being on a solid Unix foundation and all that..it's not like NT doesn't have same model, the same user/kernel isolation.....)
 
Besides..if Cygwin CVS works fine (for me and I think for Randy), either a) it's not the network, or 2) Cygwin has workarounds and TortoiseCVS/CVSNT do not. I doubt #2, but almost anything is possible.
Granted, I don't have TortoiseCVS/CVSNT working yet, didn't configure ssh for it.
 
At some hypothetical point I install Win95/98/NT3.x/NT4/Win2000 in virtual machines and see how Modula-3 fairs..
I know the current binaries won't work on Win95/NT3.x due to Interlocked stuff, and some dependency on new processors, same thing (ie: you could inline or statically link such functions, and work on older OS but not on a 386).
 
People should speak up if they expect pre-XP or 386/486/regular old Pentium support.
And even then, the processors continue to progress at a surprising-to-me rate, MMX, SSE, SSE2, etc.
(Not to mention AMD64..I have an unfortunate hardware situation at home there, might need to get another machine soon...or swap machines in a way I'd rather not..but this is getting ahead of things)
