Wouldn't that imply that -lm should be removed from hints.m4?

Recall: hints.m4 was a bridge between the old Apache 1.3 knowledge of
systems, and our *detection* based system (embodied in autoconf).

The latter... definitely :-)

It is a bit nicer to believe we have the right solution and then apply known
fixes, then to continue to carry around baggage which we never know is still
needed or not. In this particular case, the "failure mode" is an easy
diagnosis and fix.

Ideally, hints could go away, but realistically I doubt that :-)

I expect that over the next few days I'll remove it for the relatively
few platforms I have access to as I get a chance to verify.

Alternatively, we can just remove it across the board and pick up the
pieces when somebody with one of the obscure systems gets an
unresolved reference and we realize that we need to look for a
different function in -lm.

Are you in favor of the latter approach?

Thanks,
