Comment (by ballapete):

 The statenebt on lines #28 and #29 uses the values 5120 for TARGET_LEN,
 154 for initial_cwd_len and 15 for (sizeof dir_name). The resulting
 desired_depth is 331. `configure` is able to create the "confdir-14B---"
 subdirectory and a depth of 57 "confdir-14B---" levels. If I make
 `desired_depth` to equal 57 then the directory hierarchy can be
 successfully removed and it is still found:

 {{{
 checking whether getcwd succeeds when 4k < cwd_length < 16k... yes
 }}}

 The resulting `lib/config.h` is still the same as before.

 I determined `desired_depth` by outputting its value into a file from the
 `conftest` programme and also by couting the directories in "confdir-
 14B---". The patch file will be added.
