OK.  But if we are dropping v2.01, please also remove the code in
msdos.c and dosfns.c, and also in msdos/sed2v2.inp, that caters to
v2.01 and older versions.

We should also mention in msdos/INSTALL than only version 2.02 and
later are supported.

Finally, config.bat should have its test of the DJGPP version updated
to fail v2.01 and older versions.

TIA
