My gut says if we cannot solve this trivial problem over the course of three+
months due to a utter lack of competency in autoconf (and lack of time by
the small handful who understand it), perhaps the project should consider
alternatives to autoconf as we start looking down the road at APR 2.0.0?

Does anyone have any positive experiences with other configuration and feature
detection tools?
