Are you sure this difference is not because of a different configuration
of Bash? IIRC, Bash has an option to change its behaviour regarding
this. From a (probably old) Bash Info-file:

Node: Bash Variables
...
`nolinks'
     If present, says not to follow symbolic links when doing commands
     that change the current working directory.  By default, bash
     follows the logical chain of directories when performing commands
     such as `cd' which change the current directory.

     For example, if `/usr/sys' is a link to `/usr/local/sys' then:
          $ cd /usr/sys; echo $PWD
          /usr/sys
          $ cd ..; pwd
          /usr

     If `nolinks' exists, then:
          $ cd /usr/sys; echo $PWD
          /usr/local/sys
          $ cd ..; pwd
          /usr/local

     See also the description of the `-P' option to the `set' builtin,
     *Note The Set Builtin::.
...
Node: The Set Builtin
...
    `-P'
          If set, do not follow symbolic links when performing commands
          such as `cd' which change the current directory.  The
          physical directory is used instead.

Maybe we should leave this option to Bash, not libc.
