I guess it could if we introduce a DRIVE_SEPARATOR or a third
directory separator.  DOS type systems effectively have three: '\',
'/' and ':'.

I wonder why alpha VMS ignores '>' and ':'.  I can guess that '>' is
used infrequently.  I am told there is no difference between file
name conventions on the alpha and vax.

I also just noticed the VMS FILE_NAME_NONDIRECTORY translates the name to
lower case.  Thus, it now looks like we need to keep file_name_nondirectory
because it is functionally different from basename under vax VMS.  Does
the alpha port need to define FILE_NAME_NONDIRECTORY?

The argument to file_name_nondirectory shouldn't be const.  The protos
need to change.

The PATH_SEPARATOR should be ',' for VMS.  This isn't defined for either
the alpha or vax.
