# when Configure runs. (If you already have "real" source files, this won't

You will get a failure on lib/posix.t test 16 because ungetc() on
stdin does not work if no characters have been read from stdin.
If you type a character at the terminal where you are running
the tests, you can fool it into thinking it worked.
