+ fdopendir: fix bug on MacOS X when low on file descriptors
+
+ * lib/fdopendir.c (REPLACE_FCHDIR): #define to 0 if not defined.
+ (fdopendir_with_dup, fd_clone_opendir): Now have extra CWD arg.
+ All callers changed.
+ (fdopendir): Invoke save_cwd at the top level, not after using
+ multiple dup() calls to use up file descriptors. Then retry
+ fdopendir_with_dup. This avoids failure with EMFILE if FD is 1
+ less than the maximum number of open file descriptors, because
+ save_cwd fails with errno == EMFILE. Problem reported by tsteven4
+ on Mac OS X 10.6.4 for tar 1.24

+ fdopendir: fix a bug on systems lacking openat and /proc support
+ OpenBSD 4.7 is one such system. The most noticeable effect was
+ failure of any application making nontrivial use of fts: rm, du,
+ chown, chmod etc. E.g., "mkdir -p a/b; ./rm -rf a" would fail with
+ ./rm: traversal failed: `a': Bad file descriptor
+ Debugging that, you see that even though FD 6 was closed just
+ prior to the opendir call in fd_clone_opendir, its resulting
+ dir->dd_fd was 8, rather than the expected value of 6:
+
+ Breakpoint 3, fdopendir_with_dup (fd=6, older_dupfd=-1) at fdopendir.c:93
+ 93 close (fd);
+ (gdb) n
+ 94 dir = fd_clone_opendir (dupfd);
+ (gdb) n
+ 95 saved_errno = errno;
+ (gdb) p dir->dd_fd
+ $11 = 8
+
+ Notice how it closes FD 6, then gets a DIR* pointer using FD 8.
+ The problem is that on OpenBSD, fd_clone_opendir has to resort
+ to using the old-style save/restore CWD mechanism, due to its
+ lack of openat/proc support, and *that* would steal the FD (6)
+ that opendir was supposed to use.
+
+ The fix is to squirrel away the desired FD so that save_cwd uses a
+ different one, and then free the dest FD right before calling opendir.
+ That guarantees opendir will use the required file descriptor.
+
+ * lib/fdopendir.c (fd_clone_opendir): Handle the above.
