http://bugs.python.org/issue10782

  in printf

Solved issues
=============

http://bugs.python.org/issue433537
  better cross-compilation support

http://bugs.python.org/issue2513
  64bit cross compilation on windows

http://bugs.python.org/issue1115
  Minor Change For Better cross compile

Those overlapping bugs encompass 10 to 15 users interested in
cross-compilation, but not always in understanding CPython policy (i.e.
targeting 3.3 and packaging, not distutils in 2.6) or politeness <wink>.
 See also http://kegel.com/crosstool/python.html and
http://mail.python.org/pipermail/distutils-sig/2004-October/004209.html
Some patches modify the configure script, other the Windows project
thing files, and the more pervasive make changes in distutils.

The most experienced core dev about those matters is Martin von Löwis;
other core devs who make reviews are Roumen Petrov and Gregory P. Smith
(who’s recently been removing his name from nosy fields).  Mark Hammond,
Thomas Heller and Trent Nelson have knowledge on cross-compilation on
Windows.

Hope this helps.
