* Core and Builtins
- sys.platform is now always 'linux2' on Linux, even if Python is compiled on Linux 3.
- Accept bytes for the AST string type. This is temporary until a proper fix in 3.3.
- The distutils commands bdist_dumb, bdist_wininst and bdist_msi now respect a --skip-build option given to bdist.
- Fix crash in zlib module due to version mismatch.
* Extension Modules
- Fix a crash when ctypes.create_string_buffer(0) was passed to some functions like file.write().
