Nope.  There are systems where "./foo" is a valid filename but has
nothing to do with a file named "foo" and nothing to do with directories.

Systems that conform to IEEE Std 1003.1 (POSIX) will assign the usual
UNIX meaning to the "./" part of such a filename, and others may at
their discretion, but not all C environments are POSIX environments.
