Definitively, this should be our master plan. Currently things are far
too centralistic, e.g. why on earth should Haddock know about the values
of the various EFOOBAR errno values? Tests like this belong to the
package (or sub-project) which cares about it. If it's needed at more
than one place, so be it: Autoconf's cache files would make repeated
tests very cheap.

I think so, and the only reason I haven't done so yet is laziness, IIRC. :-}
