Test case that demonstrates difference between Wine and Windows

This small program is a test case that demonstrates the behaviour difference
between Wine and Windows. On Windows the serial timeout is honoured, and the
ReadFile call returns success, with zero bytes read, once the timeout expires.

On unpatched wine, the ReadFile call returns immediately with
ERROR_BROKEN_PIPE.

Wine patched with my suggested fix behaves as Windows.
