One of the main motivations for the existence of luaconf.h is to avoid
that kind of customisation. More often than not, you want all external
libraries to be compiled with the same options of the kernel (e.g.,
you want all them to use the same numeric types), and that is hard to
ensure using external defines.

For other changes, you are wellcome to use LUA_USER_H.
