= `BOOST_OS_BSD`

http://en.wikipedia.org/wiki/Berkeley_Software_Distribution[BSD] operating system.

BSD has various branch operating systems possible and each detected
individually. This detects the following variations and sets a specific
version number macro to match:

* `BOOST_OS_BSD_DRAGONFLY` http://en.wikipedia.org/wiki/DragonFly_BSD[DragonFly BSD]
* `BOOST_OS_BSD_FREE` http://en.wikipedia.org/wiki/Freebsd[FreeBSD]
* `BOOST_OS_BSD_BSDI` http://en.wikipedia.org/wiki/BSD/OS[BSDi BSD/OS]
* `BOOST_OS_BSD_NET` http://en.wikipedia.org/wiki/Netbsd[NetBSD]
* `BOOST_OS_BSD_OPEN` http://en.wikipedia.org/wiki/Openbsd[OpenBSD]

NOTE: The general `BOOST_OS_BSD` is set in all cases to indicate some form
of BSD. If the above variants is detected the corresponding macro is also set.
