declares the functions must be included, in order to make sure the
declarations match the function signature. Make it so - which means
creating the header file in the first place.
That means luaopen_bit() doesn't need to, and shouldn't be, declared in
wslua.h.
Have make-reg.pl generate a #include of lua_bitop.h. Also fix the "this
is autogenerated" warning.
