This patch provides extended file stdio support.
As it is Solaris-specific, it is not suitable for upstream.
Note that this patch is no longer needed, since is we build Python 3 64-bit
only, but we are keeping it around as a precaution in case we need to add
32-bit support back in at some point.  If a time comes when we are certain
we will never need 32-bit support, then the patch can be removed.
