SF patch #474175 (Jay T Miller): file.readinto arg parsing bug

    The C-code in fileobject.readinto(buffer) which parses
    the arguments assumes that size_t is interchangeable
    with int:

	    size_t ntodo, ndone, nnow;

	    if (f->f_fp == NULL)
		    return err_closed();
	    if (!PyArg_Parse(args, "w#", &ptr, &ntodo))
		    return NULL;

    This causes a problem on Alpha / Tru64 / OSF1 v5.1
    where size_t is a long and sizeof(long) != sizeof(int).

    The patch I'm proposing declares ntodo as an int.  An
    alternative might be to redefine w# to expect size_t.

[We can't change w# because there are probably third party modules
relying on it. GvR]
