#1462 incomplete initializers for auto vars fail

No

I thought this was in a bug report already, but I can't find it so I probably picked it up somewhere on some mailing list or on an internet forum.

The uninitialized parts of an auto(matic) local variable are not cleared to zero when an incomplete initializer is used. E.g.

void foo(void)
{
char x[5] = { 1, 2 };
ASSERT (x[3] == 0);
}

Regression test zeropad.c has some tests for incomplete initializers but not for auto's.

    Ok, I filed this only for the record because I just fixed it in SDCC 2.8.1 #5186.
