- Fixed naming conventions; SwigPyBuiltin is used a lot - Removed use of std::vector - builtin.swg isn't included if -builtin isn't specified - Changed many feature names to use a "python:" prefix - Eliminated static vars in std_pair.i - Eliminated C++-style comments (//) - Enabled autodoc and docstring with -builtin - Fixed non-ansi generated C code - Detect and complain if two incompatible swig modules are loaded - Removed argcargvtest_runme3.py, and fixed argcargvtest_runme.py so that 2to3 handles it better - Removed anonymous namespaces - Eliminated builtin_init typemaps; consolidated functionality into SWIG_Python_NewPointerObj - Eliminate printf warnings from %U conversion character by switching to %S, which works just as well - Fixed li_std_set_runme.py for python3, which returns set members in a different order from python2 git-svn-id: https://swig.svn.sourceforge.net/svnroot/swig/branches/szager-python-builtin@12562 626c5289-ae23-0410-ae9c-e8d60b6d4f22
