configure is just a POSIX sh script, but indeed it's horrible
for portability to anything beyond *nix. I'm sure a replacement
could be written (even in .BAT) or REXX or Perl or whatever.

IMHO, there isn't much to configure. Just stick to obvious
DJGPP versions like 2.03p2 (or 2.05), nothing older.

GCC 2.7.2.3 was rebuildable on DOS back in the day. You can
then use that (allegedly) to bootstrap 2.95.3, and even 3.4.6
would still (allegedly) build with K&R C compilers. I'm
still sympathetic to those, especially 3.4.6, for various
reasons.
