On some, anyway.  That's how S5 from AT&T - at least prior to S5R4 -
implements "getcwd()", but you could have "getcwd()" be the routine that
does the work (just like "getwd()", but with bounds checking) and have
"/bin/pwd" just call it.  (SGI basically does that in recent releases,
although "getcwd()" ends up calling a BSD-flavored "getwd()" to do the
actual work).  Dunno whether S5R4 does that or not.
