We have raised the compiler requirement from time to time. With commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6"), the minimum for GCC is 4.6 now. The -Wno-pointer-sign has been here since the pre-git era. It is documented in the GCC 4.6 manual, and it is recognized by Clang and ICC as well. Let's rip off the cc-disable-warning switch, and see if somebody complains about it.
