Bad timing.  I was about to make a test release.
If anyone else has access to a Solaris 10 system (x86 or otherwise),
with Sun C, would you please try the latest snapshot?

I ran a couple quick tests, and they suggest that there's nothing
special about Solaris 10's getcwd implementation (i.e., it's not
like the linux/glibc one).  For example, /bin/pwd doesn't work
when a parent is unreadable.  Does their system-provided
getcwd have something else to recommend it?
