In the section on the "Very High Level Layer", address concerns brought up

by Edward K. Ream <edream@users.sourceforge.net> about FILE* values and
incompatible C libraries in dynamically linked extensions.  It is not clear
(to me) how realistic the issue is, but it is better documented than not.

This closes SourceForge bug #111520.

\constant{Py_file_input}, and \constant{Py_single_input}. These are
described following the functions which accept them as parameters.
Note also that several of these functions take \ctype{FILE*}
parameters. On particular issue which needs to be handled carefully
is that the \ctype{FILE} structure for different C libraries can be
different and incompatible. Under Windows (at least), it is possible
for dynamically linked extensions to actually use different libraries,
so care should be taken that \ctype{FILE*} parameters are only passed
to these functions if it is certain that they were created by the same
library that the Python runtime is using.
