Oops. Need to check not only that HAVE_DECL_ISINF is defined, but also
...
that it's equal to 1. (If isinf isn't defined, HAVE_DECL_ISINF is
defined to be 0, rather than being undefined.)

isinf and isnan are macros, not functions; fix configure script
...
to use AC_CHECK_DECLS instead of AC_CHECK_FUNCS for these.

I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.
...
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)
