[Bug-gnulib] stdbool.h: support for BeOS

[Bruno Haible]

Hi,

Currently, using

  #include <stdbool.h>
  #include <sys/socket.h>

leads to a compilation error on BeOS, because some auxiliary file included
by <sys/socket.h> defines the type 'bool' but not '_Bool'.

I've committed this fix, that works by forcing the inclusion of that
auxiliary file (via <OS.h>) and reusing its 'bool' type.
