[Bug target/42159] app compiled with 4.4.2 SIGABRTs after a trivial nested throw/stack unwinding

Well, I think my scheme worked: I have succeeded in reverse engineering the
4.4.2 fink scripts into something I could use to build 4.5 trunk against the
prerequisite libs installed via fink.

Indeed, 4.5 trunk does not appear to have this issue:
