``repr(x)`` for a float x returns a result based on the shortest decimal
string that's guaranteed to round back to x under correct rounding (with
round-half-to-even rounding mode).  Previously it gave a string based on
rounding x to 17 decimal digits.  repr(x) for a complex number behaves
similarly.  On platforms where the correctly-rounded strtod and dtoa code is
not supported (see below), repr is unchanged.

On almost all platforms: float-to-string and string-to-float conversions
within Python are now correctly rounded.  Places these conversions occur
include: str for floats and complex numbers; the float and complex
constructors; old-style and new-style numeric formatting; serialization and
deserialization of floats and complex numbers using marshal, pickle and
json; parsing of float and imaginary literals in Python code;
Decimal-to-float conversion.

The conversions use a Python-adapted version of David Gay's well-known
dtoa.c, providing correctly-rounded strtod and dtoa C functions.  This code
is supported on Windows, and on Unix-like platforms using gcc, icc or suncc
as the C compiler.  There may be a small number of platforms on which
correct operation of this code cannot be guaranteed, so the code is not
used: notably, this applies to platforms where the C double format is not
IEEE 754 binary64, and to platforms on x86 hardware where the x87 FPU is set
to 64-bit precision and Python's configure script is unable to determine how
to change the FPU precision.  On these platforms conversions use the
platform strtod and dtoa, as before.

Backport round implementation from Python 3.x.  ``round()`` now uses the
correctly-rounded string <-> float conversions described above (when
available), and so produces correctly rounded results that will display
nicely under the float repr.  There are two related small changes: (1) round
now accepts any class with an ``__index__()`` method for its second argument
(but no longer accepts floats for the second argument), and (2) an
excessively large second integer argument (e.g., ``round(1.234, 10**100)``)
no longer raises an exception.

counterpart, override the co_filename attributes of all code objects if the
original filename is obsolete (which can happen if the file has been
renamed, moved, or if it is accessed through different paths).  Patch by
Ziga Seilnacht and Jean-Paul Calderone.

Fix various struct.pack inconsistencies for the integer formats

- Packing a float now always gives a Deprecation Warning.  Previously it
only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

- If x is not an int, long or float, then packing x will always result in
struct.error.  Previously an x with an __int__ method could be packed by
'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
__long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
neither __int__ nor __long__, TypeError used to be raised (with a
confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
struct.error in other cases.

Note: as of Python 2.7 beta 1, the above is out of date.  In 2.7 beta 1, any
argument with an __int__ method can be packed, but use of this feature
triggers a DeprecationWarning. (See also: bpo-1741130)
