Do I understand you correctly that you know that your gpp package
doesn't work on 386s? "Work" here means that the compiler _and_ the
executables it builds do run on a 386. (I know that some older version
didn't make workable 386 executables.)

No, I misunderstood something:
	Then I guess we don't know if it does work or not. But 1 below
	should be considered.

Yes, that's what you're saying:
	Well, IMO:
	1. You really really really should point out that things built
	   with gpp only is for 486 (or Pentium or whatever) or later.

	2. Shouldn't it be compiled for i386-pc-msdosdjgpp then so
	   that it potentially does work 386s?


If the bug still is in gpp even when built for i386-pc-msdosdjgpp,
then we have to wait to get it fixed, but 1 still applies. Plus we
might need to change some texts which say "DJGPP requires at least a
386" adding ", 486 (or whatever) for C++ programs".


Right,
