I made a new release of zope.i18nmessageid (3.5.3) persuant to a conversation that took place on this list a few weeks ago related to switching back to overriding build_ext to allow the package to work on Jython and other CPython platforms. Would someone be kind enough to build and upload new Windows binaries? Here's the related changelog entries: 3.5.3 (2010-08-10) ------------------ - Made compilation of C extension optional again; 3.5.1 broke this inasmuch as this package become unusable on non-CPython platforms. Making the compilation of the C extension optional again implied removing ``setup.py`` code added in 3.5.1 which made the C extension a setuptools "Feature" and readding code from 3.5.0 which overrides the distutils ``build_ext`` command. - Move pickle equality tests into a unittest.TestCase test to make it easier to condition the tests on whether the C extension has been compiled. This also makes the tests pass on Jython.
