Adding more decl attribute code

Hey I just been needing to get access to certain attributes of functions like DECL_EXTERNAL or DECL_STATIC etc would e quite nice to have. And i see i add in: // generate-tree-c.py add_simple_getter('external', 'gcc_python_make_wrapper_tree(DECL_EXTERNAL(self->t))', "The decl_external value") But these attributes return an unsigned char:1 so just a simple True and False. I dont know what function i should be using to wrap a simple value for this i feel quite lost in the code. --Phil
