Euk! Wish they asked for my opinion before... Problem is that 1.1.4 is
experimental and there's no reliable way to detect the version of Speex
(at least not in 1.1.4) installed. Also, the symbols are the same, just
with a different type. Unless you do some very ugly hacks, your best
choice may be to require 1.0.x or 1.1.6 (or later).
