Note that for maximum unix compatibility, we should probably do this:

In the crt0 code, compare the path to our executable to the $PATH.  If
we were found in some directory already on the $PATH, omit the
directory and leave the basename.  If we were not found on the $PATH,
leave the full path alone.

Another thing we might consider is to remove the drive specifier if it
happens to be the current drive.  For many cases, this will make it
look unix-like enough to work with dos-unaware programs.
