Issue #7117 (backport py3k float repr) continued:
...
- add double endianness detection to configure script
- add configure-time check to see whether we can use inline
assembly to get and set x87 control word in configure script
- add functions to get and set x87 control word in Python/pymath.c
- add pyport.h logic to determine whether it's safe to use the
short float repr or not

Issue #4575 : fix Py_IS_INFINITY macro to work correctly on x87 FPUs.
...
It now forces its argument to double before testing for infinity.

Use C99 'isfinite' macro in preference to BSD-derived 'finite' function.

Fix HAVE_DECL_ISINF/ISNAN test (again).

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 :)
