  Applied my patch #1455 with some extra fixes for VS 2005
  The new msvc9compiler module supports VS 2005 and VS 2008. I've also fixed build_ext to support PCbuild8 and PCbuild9 and backported my fix for xxmodule.c from py3k. The old code msvccompiler is still in place in case somebody likes to build an extension with VS 2003 or earlier.
  I've also updated the cygwin compiler module for VS 2005 and VS 2008. It works with VS 2005 but I'm unable to test it with VS 2008. We have to wait for a new version of cygwin.

  Faster _fix function, and some reordering for a more elegant
  coding. Thanks Mark Dickinson.

  Issue #1727780: Support loading pickles of random.Random objects created
  on 32-bit systems on 64-bit systems, and vice versa. As a consequence
  of the change, Random pickles created by Python 2.6 cannot be loaded
  in Python 2.5.

+
+System Functions
+================
+
+These are utility functions that make functionality from the :mod:`sys` module
+accessible to C code.  They all work with the current interpreter thread's
+:mod:`sys` module's dict, which is contained in the internal thread state structure.
+
+.. cfunction:: PyObject *PySys_GetObject(char *name)
+
+   Return the object *name* from the :mod:`sys` module or *NULL* if it does
+   not exist, without setting an exception.
+
+.. cfunction:: FILE *PySys_GetFile(char *name, FILE *def)
+
+   Return the :ctype:`FILE*` associated with the object *name* in the
+   :mod:`sys` module, or *def* if *name* is not in the module or is not associated
+   with a :ctype:`FILE*`.
+
+.. cfunction:: int PySys_SetObject(char *name, PyObject *v)
+
+   Set *name* in the :mod:`sys` module to *v* unless *v* is *NULL*, in which
+   case *name* is deleted from the sys module. Returns ``0`` on success, ``-1``
+   on error.
+
+.. cfunction:: void PySys_ResetWarnOptions(void)
+
+   Reset :data:`sys.warnoptions` to an empty list.
+
+.. cfunction:: void PySys_AddWarnOption(char *s)
+
+   Append *s* to :data:`sys.warnoptions`.
+
+.. cfunction:: void PySys_SetPath(char *path)
+
+   Set :data:`sys.path` to a list object of paths found in *path* which should
+   be a list of paths separated with the platform's search path delimiter
+   (``:`` on Unix, ``;`` on Windows).
+
+.. cfunction:: void PySys_WriteStdout(const char *format, ...)
+
+   Write the output string described by *format* to :data:`sys.stdout`.  No
+   exceptions are raised, even if truncation occurs (see below).
+
+   *format* should limit the total size of the formatted output string to
+   1000 bytes or less -- after 1000 bytes, the output string is truncated.
+   In particular, this means that no unrestricted "%s" formats should occur;
+   these should be limited using "%.<N>s" where <N> is a decimal number
+   calculated so that <N> plus the maximum size of other formatted text does not
+   exceed 1000 bytes.  Also watch out for "%f", which can print hundreds of
+   digits for very large numbers.
+
+   If a problem occurs, or :data:`sys.stdout` is unset, the formatted message
+   is written to the real (C level) *stdout*.
+
+.. cfunction:: void PySys_WriteStderr(const char *format, ...)
+
+   As above, but write to :data:`sys.stderr` or *stderr* instead.
