    Subject[PATCH 61/64] Makefile: Enable -Warray-bounds
    Date
    With the recent fixes for flexible arrays and expanded FORTIFY_SOURCE
    coverage, it is now possible to enable -Warray-bounds. Since both
    GCC and Clang include -Warray-bounds in -Wall, we just need to stop
    disabling it.
