According to <http://sources.redhat.com/ml/newlib/2004/msg00478.html>, the
patch was checked in on Oct 26.  Cygwin uses the latest version of newlib.
Cygwin 1.5.12-1 was released on Nov 10, so it should contain this patch.

You can verify this by downloading the Cygwin source package, and looking
at newlib/libc/stdio/fread.c.
