Why does -pthread necessarily force selection of one specific
threading library? All it means is that it is that the program uses
posix threads, at least traditionally. How FreeBSD causes that to
happen is an interesting implementation detail for some, but irrelvant
for most ports. Couldn't -pthread be made to give the user the
default threading package, and for those that matter a more specific
one can be specified?
It is insane to have FreeBSD be different than all other systems for
this trivial reason. Why fix everthing in the world when allowing
-pthread to be a noop would solve the problem? Seems like we're being
overly picky for no real gain. I guess I just don't understand.
