This patch makes sed 4.9 build correctly without encountering errors regarding #pragma GCC diagnostic related errors in functions. Since GCC 4.2 does not support diagnostics, and these are useless and only for supressing warnings, this patch comments out the unneeded lines containing these. These patches should satisfy the needs of most people using GCC 4.2.
