: I plan on changing thread library compatibility for FreeBSD

FYI: gcc 3.4 will have -pthread accross the board to mean "use
whatever the right threading package/library/etc for your system is."
It would be unwise of us to deviate substantially from that. The
changelog also suggests that the right #defines for your system will
be added when -pthread is specified on the command line for compiles
(as opposed to linking).
