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

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

  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.)

  Add autoconf test to detect x87-style double rounding, as described in
  issue #2937.  This information can be helpful for diagnosing platform-
  specific problems in math and cmath.  The result of the test also
  serves as a fairly reliable indicator of whether the x87 floating-point
  instructions (as opposed to SSE2) are in use on Intel x86/x86_64 systems.

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