No, the GNU ld man page contains:

<quote>
For compatibility with other ELF linkers,  if  the  -R
option  is followed by a directory name, rather than a
file name, it is treated as the -rpath option.
</quote>

And indeed the Tru64 ld only knows -rpath which seems to confirm the GNU ld 
man page.

Is it doing the same as the GNU ld's -R parameter, with the same handling 
of directory arguments as a special case?

That's what I think, yes.
