lcode.c also needs it now (for constant-expression evaluation; yes,
another novelty in beta...). But the main point is that, if you change
lua_Number (or the definitions of some airthmetic operations), they
may not need math.h anymore. We want to be able to correct that only
changing luaconf.h.

As you are already changing those modules, you can include math.h in
them before including the lua headers :)
