The Linux man page says:

: RETURN VALUE
:        If there  is  no  error,  it  returns  a  pointer  to  the
:        resolved_path.
:
:        Otherwise   it  returns  a  NULL  pointer  and  places  in
:        resolved_path the absolute pathname of the path  component
:        which  could not be resolved. The global variable errno is
:        set to indicate the error.

However, I don't actually need this behaviour. I thought it was part
of the "standard" functionality of realpath(), but if it isn't on
other systems, you probably don't need to implement it on DJGPP.
