Note that the original thing I proposed (speex_lib_ctl and
SPEEX_LIB_GET_VERSION, ...) is a run-time method. Note however that you'd
still
have to dlopen the library since can't just do:
if (call_is_allowed)
    speex_encode_int(...);

because then it won't link.

Runtime methods would be nice too, for prebuilts to be able to determine
what they can call and whatnot.

Yeah, I understand that.

I wonder if there's a way to "weak-link" against libraries on
Linux/GNU-ld-so?  The idea is that a symbol lookup/relocation isn't
performed until the call is actually MADE, rather than merely referenced.

Anyhow, that's a different problem with a different mailing list. :)
