>Description:
Peter Holm (pholm%FreeBSD.org@localhost) discovered that h_memset's memset call was being compiled out by an earlier version of clang (3.3.x/3.4.x) -- this change uses the result of the memset (b[0]) to ensure that the call to memset isn't over ambitiously optimized out by the toolchain.
