Hi,

I think that you are using bash's `internal' cwd and not running /bin/pwd:
Here is the output of running you commands on bash over linux and then
bash over solaris 6:

linux:/tmp/crap2/crap1$ uname -a
Linux school 2.2.14 #2 SMP Thu Feb 17 23:43:36 EST 2000 i686 unknown
linux:~$ mkdir -p /tmp/crap/crap1 ; ln -s /tmp/crap /tmp/crap2 ; cd /tmp/crap2/crap1 ;
linux:/tmp/crap2/crap1$ pwd
/tmp/crap2/crap1
linux:/tmp/crap2/crap1$ /bin/pwd
/tmp/crap/crap1
linux:/tmp/crap2/crap1$

solaris:/tmp/crap2/crap1# uname -a
SunOS sun00854 5.6 Generic_105181-11 sun4u sparc
solaris:~# mkdir -p /tmp/crap/crap1 ; ln -s /tmp/crap /tmp/crap2 ; cd /tmp/crap2/crap1 ;
solaris:/tmp/crap2/crap1# pwd
/tmp/crap2/crap1
solaris:/tmp/crap2/crap1# /bin/pwd
/tmp/crap/crap1
solaris:/tmp/crap2/crap1#
