Re: [bug-gawk] builtin.c:warning: shifting a negative signed value is undefined

[Sergey Tselikh]

It is quite possible, that ``~ (t) 0'' in that macro should be ``(t) 1''.
On two's complement (and ones' complement) systems a signed integer has minimum value when its most significant bit is set to 1 and rest of bits are set to 0. Only one bit with value 1 is needed on the left side of ``<<'' operation.

Hi,

Just in case it would be helpful: attached 2 compiler warnings which I
am getting since I recently upgraded to macOS 10.12
