There is no such word as "rare".

Sure it does, esp. (and only) if you want to run DOS programs! And
that"s considered a valuable feature except by very young kids and old
snobs.

Which meant absolutely nothing from most users perspective. Is like a Mac
with Forth based bootstrap not making every Mac users Forth experts. (or
even know what it is)
And yes, DPMI was originally created to make >640kb use over a range of OSes

I think you"re mistaken. Win 3.0 came out in 1990, and that"s where

v2 is from 1996, so that"s why. It"s much more stable and compatible
although technically DJGPP v2 has no separate extender anymore, that
part is built into the lib. It only needs and can only use DPMI (which
is a "standard"). Of course, v2 apps are bigger due to this, but then
again, go32.exe is fairly bulky too (78k), but UPX only handles...

FPC did support go32v1, but I never saw it run. When I joined in 1997/8 iirc
it was already v2. People have played with a bunch more extenders too
(pmode, watcom), but none really s...

A 386 and a 486 are different animals, e.g. LODSB isn"t much (if any)
penalty on the former but heavily slower on the latter. Granted, I"ve
never truly optimized for those processors, so I can"t say for sure,
but in other words, what was fast then ain"t as fast now. (Even GCC

From the looks of it, FPC 1.0.10 used to perhaps support v1 also
(source/rtl/go32v1 and source/rtl/go32v2). I think I"ve read that
DJGPP decided it was too much trouble to support both DPMI and e.g.
VCPI or whatever, so they didn"t bother in v2. DPMI was usually the
best way to use lots of RAM on OS/2 and Windows "back i...
