I would say so. Most things can be done with preprocessor conditionals and some redefinitions, e.g. "#define PyLong_Type PyInt_Type", etc. The method "generate_module_preamble()" in Cython's ModuleNode.py source file (from line 360 onwards) has a code block of things we found so far. http://hg.cython.org/cython-devel/file/tip/Cython/Compiler/ModuleNode.py > I believe the buffer api is supposed to be backported to 2.6?
