Explicitly truncate bswap operand to uint32_t
There are some places in git where a long is passed to htonl/ntohl. llvm doesn't support matching operands of different bitwidths intentionally. This patch fixes the build with llvm-gcc (and clang) on x86_64. Signed-off-by: Benjamin Kramer <benny.kra@googlemail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
