Subject: [PATCH] Add pragma to ignore clang warning

Compiling poll.c with clang 3.2 and "-Wall -Werror" gives the following
error message:

poll.c:456:11: error: comparison of unsigned expression < 0 is always
false [-Werror,-Wtautological-compare]
  if (nfd < 0 || timeout < -1)
        ~~~ ^ ~
        1 error generated.
        make: *** [compat/poll/poll.o] Error 1

This warning is now explicitly disabled for clang as done
already for gcc.
