[heading `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.]
