Changes (by igaztanaga):

  * milestone:  Boost 1.44.0 => Boost-1.45.0

Comment:

 FreeBSD does not define _POSIX_SEMAPHORES so Interprocess was not using
 sem_xxx for named semaphores. However FreeBSD supports sem_xxx with some
 bugs:

 http://www.freebsd.org/cgi/man.cgi?query=sem_open&apropos=0&sektion=0&manpath=FreeBSD+9-current&format=html


 BUGS
      This implementation places strict requirements on the value of name:
 it
      must begin with a slash (`/'), contain no other slash characters, and
 be
      less than 14 characters in length not including the terminating null
      character.

 Interprocess for Boost 1.45 will use sem_xxx family if FreeBSD is
 detected.
