And, in addition, "using the minimal setting" is unacceptable.  A TZ
setting of the form "EST5EDT" is *correct*, and I can't require my
users to change a perfectly valid setting because of bugs in djgpp's
libraries.  (The long form may be even more correct, but I'm 95%
certain it will break older programs which were compiled before Posix
got popular.)  I'm not even asking that the "EDT" part be honored cor-
rectly; as my initial bug report noted, emx ignores that, too.  What
it *doesn't* do (but djgpp does) is ignore the "5" when the EDT is 
present.  And, of course, emx's time/ftime values are consistent with 
its stat() values regardless of what the TZ setting is (or isn't).
DJ:  try testing in some other timezones besides Eastern.  The current 
code has that hardwired in at least two places.

Btw, thanks to Henrik for helping to debug all of this.  I grabbed
the libc sources and started poking around, but I got stuck when 
turbo_assist went off into an unknown (private?) int 21h function.
Compiling with any version of Turbo C isn't an option for me, but I
did check the MSC license and didn't find any funny no-competition
clauses, FWIW.
