I pushed to master, but the docs are out of date, so I'm updating them. I also want to run the testsuite with gcc-4.5, and finally have a look at those numpy issues. At least the bug is fixed now in 4.5: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49897 . A pretty quick fix! _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
