1. The undocumented API luaL_findtable It is no longer available in Lua 5.3 but turned out practical for this project. We added an auxiliary function "lua_protobuf_find_or_create_nested_table" in lua-protobuf.h/cc with similar implementation. And all its references are replaced by the new function, of course. 2. luaL_register It is also unavailable in Lua 5.3. We replaced it with the new API "luaL_setfuncs" for each call with a NULL "libname" param. And those with non-NULL "libname" params were replaced with a combination of "luaL_setfuncs" as well as "lua_protobuf_find_or_create_nested_table" mentioned in the first clause above, and maybe a "lua_pop", if necessary, instead. 3. lua_pushinteger for enums rather than lua_pushnumber 4. ternary conditional operator Lua API lua_pushlstring and lua_pushnil have different return types, and gcc complains if we use them as the second and the third operand for the ternary conditional operator. We changed them to "if ... else ..." statements.

1. The undocumented API luaL_findtable
It is no longer available in Lua 5.3 but turned out practical for this project. We added an auxiliary function "lua_protobuf_find_or_create_nested_table" in lua-protobuf.h/cc with similar implementation. And all its references are replaced by the new function, of course.
2. luaL_register
It is also unavailable in Lua 5.3. We replaced it with the new API "luaL_setfuncs" for each call with a NULL "libname" param. And those with non-NULL "libname" params were replaced with a combination of "luaL_setfuncs" as well as "lua_protobuf_find_or_create_nested_table" mentioned in the first clause above, and maybe a "lua_pop", if necessary, instead.
3. lua_pushinteger for enums rather than lua_pushnumber
As the title says.
4. ternary conditional operator
Lua API lua_pushlstring and lua_pushnil have different return types, and gcc complains if we use them as the second and the third operand for the ternary conditional operator. We changed them to "if ... else ..." statements.
