  - Emese fixed an assert in the size overflow plugin that could trigger while compiling on 32 bit archs, reported by spender
  - Emese fixed the handling of more intentional overflows in unsigned/signed casts, reported by minipli
  - updated the mrproper target for the new location of the overflow plugin headers, by minipli
  - fixed an off-by-one in the prefault code in access_ok on x86, reported by Roy Li <rongqing.li@windriver.com>
    it'd cause a prefault attempt on address 0 and other unmapped addresses and fail the current syscall
  - updated gcc-common.h
