The proposed patch is correct; no extension module should use PyAPI_ for its own symbols.

Fix committed in 2.7 and 3.2. 3.3 shouldn't be affected. Thank you!

Final 2.7.3 didn't get the fix. Checked http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.xz

Yes, the 2.7.3 branch was cut long before the fix (end of February) so it was not included.
