The oemacs shell-command runs the shell specified by the SHELL environment
variable (or at least that's what the info files say).  I'll admit that I
don't actually have a shell environment variable set, but it would not be
unreasonable for me to have done so.

There are two uses for djgpp: (1) port unix software to DOS and (2) get
around the 640K limit in new or existing DOS software.  I doubt anyone has
any statistics on which use is more common, but it sounds like your use is
primarily #1 while mine is primarily #2.
