Consider the use of
https://github.com/hishamhm/lua-compat-5.2/
Note the c-api subdirectory. It was contributed by Tomás Guisasola
Gorham based on his compatibility work for the MD5 library and
extended by Philipp Janda for the backport of bit32. Little by little,
it can grow to make the conversion of C extensions an easier process.

Looking at your code, the most delicate part is your use of
luaL_Buffer fields (that might need some inescapable #define's). If
you spot anything else that can be wrapped by compat-5.2 instead,
consider yourself encouraged to contribute to our compatibility
interface.
