Re: BUG #2162: Same as bug #1679 - finite() - unresolved symbol

I will also try these tests with '-O2' tomorrow (compile conftest and look =
if the symbol is still inside). I will even try more aggressive optimizatio=
n.

Good point.  The isinf() test probably has the same failure mode.

There is also the sigsetjmp() test, but since that has side-effects,
it doesn't seem very much at risk of being aggressively optimized.
I don't see any other cases where we're avoiding AC_CHECK_FUNC.
