Looks good thanks! I ran the modified script using 'make everything' in
the directory (after setting up a python venv to install ctypesgen) and
it didn't break anything. (There were some harmless errors output by
ctypesgen due to failing to parse some GCC extensions, but those are
nothing to do with this patch and the generated C files are OK.)
