Subject: [PATCH] cmake: Disable nonnull-compare warning on gcc
GCC finds a legit warning which clang does not on code like this
class Message;
void SendResponse(Message & aMessage)
{
if ((&aMessage) != nullptr) { return; }
}
Perhaps it should be fixed upstream but for now disable treating this
warning as error when using gcc
Upstream-Status: Pending
