[New-bugs-announce] [issue39237] Redundant call to round in delta_new

[Alex Henrie]

New submission from Alex Henrie <alexhenrie24 at gmail.com>:

The delta_new function in _datetimemodule.c currently contains the following code:

    /* Round to nearest whole # of us, and add into x. */
    double whole_us = round(leftover_us);
    int x_is_odd;
    PyObject *temp;

    whole_us = round(leftover_us);

The second call to the round function produces the same result as the first call and can therefore be safely eliminated.
