I've just verified that /bin/pwd exists on the following OSs:
AIX 4.3
HP-UX 11
IRIX 6.5
OpenBSD 3.1
RedHat Linux 7.2
Solaris 8
Does anyone know of any OSs where /bin/pwd does NOT exist?

I've never seen a shell that doesn't use $PWD, but resetting it
globally might have some bad side-effects as well. For example, the
user would probably want $abs_builddir to be set using the symlink
path, not the real path.
The best behavior would probably be to use "." for abs_builddir and
abs_top_builddir, but "`/bin/pwd`" for abs_srcdir and abs_top_srcdir.
If no one has any other ideas, I'll throw together a patch that
implements this.
