I can't answer your other two questions, but I'll take a shot at this
one: I've seen scripts that try to compile trivial code that uses
something questionable, and reads the response from the compiler to see
if it worked. Then it configures the real project to use it or not.

(I saw this used by VMware Tools, when compiled under Linux. I'm sure
other Linux-based projects use it too.)

I doubt that's what you were asking for, but if the library isn't
designed to give you that information, it's the only way I know of to
determine it.
