I didn't do a system call.  I doubt that the system call makes
any difference.  I.e., it just respawns a new instance of
command.com etc.  So, I just entered 'ver' at the command line.

DOSBox ver reports:
   "DOSBox version 0.74. Reported DOS version 5.00."

dosemu ver reports the MS-DOS version installed on the
partition that was mounted by dosemu:
   "Windows 98 [Version 4.10.2222]"

Obviously, that has nothing to do with Linux dosemu, which
just provides the console with, not the DOS which is executed.
That is MS-DOS v7.10 which is part of Windows 98/SE.  I.e.,
if I had FreeDOS on a partition and booted it via dosemu,
'ver' should return whatever FreeDOS reports.

So, some emulation will return different results, but other
emulation just returns the results for the installed version
of DOS.
