Subject: Bug report:  PWD environment variable broken!
X-Mailer: VM 6.62 under 21.0 "Pyrenean63" XEmacs Lucid (beta63)

On some platforms, the PWD environment variable is not being properly
updated after a cd.  This is the environment variable, not the
internal PWD variable.

Here is some output on a variety of systems for this command sequence:

uname -a; echo $ZSH_VERSION; cd ~/x/build;  env | grep PWD | grep -v OLDPWD

Conclusions:  3.1 Seems to be broken on Linux and BSDI.  A serious bug.

I tried to downgrade to 3.0.5.

3.0.5 on BSDI coredumps on invocation. 

On Linux 3.0.5 failed to build:

gcc -c -I.. -I. -I.  -DHAVE_CONFIG_H -Wall -Wno-implicit -Wmissing-prototypes -O2 builtin.c
builtin.c:4279: macro `dup' used with just one arg

:-(

It's sad to see my favorite shell so buggy!
