Even more VMS tweakage from Charles Lane:

Tweak #1:  splitdir only works on directory part of filespec,
           split off volume first
Tweak #2:  VMS pre-7.0's $ENV{'HOME'} is not settable
	   (it's a horrible kludge in the run-time library,
           improved in later versions). Check the
           $Config{'d_setenv'} flag before attempting to set it.
