  Issue #7518:  Move substitute definitions of C99 math functions from
  pymath.c to Modules/_math.c.
........

The SSE2 detection and enabling could potentially cause

2009-04-18T20:17:52+00:00

problems for binary distributions of Python in situations
where the build machine has SSE2 but the target machine
does not.

Therefore, don't enable SSE2 instructions automatically on x86.

Add check for C99 round function to configure, and define

a fallback function if round doesn't exist.

Issue #1580: use short float repr where possible.

2009-04-16T19:52:09+00:00

 - incorporate and adapt David Gay's dtoa and strtod
   into the Python core
 - on platforms where we can use Gay's code (almost
   all!), repr(float) is based on the shortest
   sequence of decimal digits that rounds correctly.
 - add sys.float_repr_style attribute to indicate
   whether we're using Gay's code or not
 - add autoconf magic to detect and enable SSE2
   instructions on x86/gcc
 - slight change to repr and str:  repr switches
   to exponential notation at 1e16 instead of
   1e17, str switches at 1e11 instead of 1e12

  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 :)
