Re: [boost] Patch: is_convertible with builtin numeric types and gcc

One thought I had:

Isn't it true that anything convertible from float is also convertible from
int?
When the first argument is a floating type, we could check to see whether
int is convertible to the 2nd argument.

There might be issues here with reference parameters; I don't know.
