I don't think Robert was "bashing DOS". His comment was advice based
on the fact that you have to be running 32-bits to run GNAT and that it
makes sense to use a "native" 32-bit OS instead of a 16-bit OS with
a 32-bit extender on it. NOTE: the word "development" in his quote.
As for target systems.... knock yourself out. We are developing
on WinNT and targeting a 2"x3" 386EX board (and have targeted PC's
running DOS too). Of course if you only have one box, and don't
want to reboot often, then DOS host/target is probably the way to go.
You just have to judge for yourself if your time lost by using DOS
as a development system is worth less than then the cost of a
second "embedded DOS box" (probably under $500).
