Yep, you're right. It's a bug in version 2 of SVR4. It is being
addressed in version 3. The problem is the getwd() in
/usr/ucblib/libucb.a uses the S5 filesystem data structures rathern
than the UFS ones. There are 2 versions of opendir/readdir, one in
libc and the other in libucb. The return slightly different
structures. You should be able to work around the problem if you
recompile not using /usr/ucbinclude and /usr/ucblib/libucb.a. Using
the standard System V libraries and not the compatibility stuff should
keep you out of trouble for now.
