You first need to get rid of any code that assumes that siget_t is an
(unsigned) integer. Use macros to abstract the access to the new sigset_t
so that you don't replace one assumption with the other...

You can't use any BSD or FreeBSD specific types (such as u_int32)t) in
publicly visible types (such as sigset_t). It breaks programs because it's
not ANSI and/or Posix.
