The function Py_UniversalNewlineFgets currently initializes the variable c to 'x' and then overwrites it without ever reading that value back. There used to be code that read back c's initial value, but it was commented out by commit b94767ff44edf5d461d7cb1c8eb5160f83886358 (bpo-8914) in 2011. So at this point, removing the dead initialization will not trigger a compiler warning or cause any other undesired behavior.
