This is not about "proper" Lua. We can add these casts in the next
release.
The first cast, for HUGE_VAL, seems to be pure pedantism of the compiler.
At least in IEEE 754, the conversion of HUGE_VAL to float does not lose
any "precision" (like a conversion of 1.0 from double to float).
About the second cast, we actually have not understood what is the issue.
