To some degree, it depends on whether you are okay with $PWD being logical
on platforms where pwd behaves like the posix 'pwd -P'; however, since
autoconf documents that you can't reliably expect either 'pwd -L' or 'pwd
- -P', you have to deal with both anyway.  But I personally don't know how
likely you are to hit a shell that forgets to assign PWD.
