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 :)

Fixed a wrong assumption in configure.in and Include/pyport.h. The is finite function is not called isfinite() but finite(). Sorry, my fault. :)

Applied patch #1635 : Float patch for inf and nan on Windows (and other platforms).

Mostly revert this file to the same version as before. Only force setting

of PY_FORMAT_SIZE_T to "l" for Mac OSX. I don't know a better define
to use. This should get rid of the warnings on other platforms and Mac too.

Fix %zd string formatting on Mac OS X so it prints negative numbers.
...
In addition to testing positive numbers, verify negative numbers work in configure.
In order to avoid compiler warnings on OS X 10.4, also change the order of the check
for the format character to use (PY_FORMAT_SIZE_T) in the sprintf format
for Py_ssize_t. This patch changes PY_FORMAT_SIZE_T from "" to "l" if it wasn't
defined at configure time. Need to verify the buildbot results.
Backport candidate (if everyone thinks this patch can't be improved).

Added a new macro, Py_IS_FINITE(X). On windows there is an intrinsic for this and it is more efficient than to use !Py_IS_INFINITE(X) && !Py_IS_NAN(X). No change on other platforms

Remove INT_MIN that came from the AST merge.

INT_MIN is used in Python/compile.c, but it was also used
in Objects/abstract.c Python/getargs.c. If we need it for compile.c,
we can get it from the same place as the other files.

Merge ast-branch to head

This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.
The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Introduced a Py_IS_NAN macro, which probably works on the major platforms

today. pyconfig.h can override it if not, and can also override
Py_IS_INFINITY now. Py_IS_NAN and Py_IS_INFINITY are overridden now
for Microsoft compilers, using efficient MS-specific spellings.

or broken by basic ctype functions in 4.4BSD descendants. This

the POSIX-incompatibility for their backward-compatiblities in near
future.

Bug #794140 : cygwin builds do not embed

The embed2.diff patch solves the user's problem by exporting the missing
symbols from the Python core so Python can be embedded in another Cygwin
application (well, at lest vim).

This patch enables the building of Cygwin Python with a static core
...
which still supports shared extensions. It takes advantage the latest
Cygwin binutils (i.e., 20030901-1) which can export symbols from
executables:
http://cygwin.com/ml/cygwin-announce/2003-09/msg00002.html
Additionally, it finally lays to rest the following mailing list
subthread:

I tested the patch under Red Hat Linux 8.0 too

Patch #661760 : Cygwin auto-import module patch
...
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.
Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Apparently FreeBSD enables some HW floating-point exceptions by default.
...
This can cause core dumps when Python runs. Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions. This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.
