# When rmdir fails because the specified directory is not empty, it sets
# errno to some value, usually ENOTEMPTY.  However, on some AIX systems,
# ENOTEMPTY is mistakenly defined to be EEXIST.  To work around this, and
# in general, to avoid depending on the use of any particular symbol, this
# test runs a test to determine the actual numeric value.
