Update of /cvsroot/src/lib/libc/gen
In directory nb00:/tmp/cvs-serv953

Modified Files:
        getcwd.c 
Log Message:
backout parts of the lite2 merge; it causes undesirable lossage:
* $PWD was used if it appeared ``correct''. this `enhancment' was
  not documented in getcwd(3), and caused problems for pwd(1) (which
  uses getcwd(3)), and in turn <bsd.obj.mk> (which uses pwd) when $PWD
  is set to the logical path instead of the real path (e.g, symlink
  /usr/src -> /z/NetBSD-current/src).
  [$PWD is set to the logical path by tcsh(1) with set symlinks=expand]
* as getcwd() without the $PWD code is just a wrapper to getcwd_physical(),
  rename the latter to the latter. hack realpath() to use the getcwd().
