[Bug other/25493] New: missed warning about possible loss of data during conversion.

["pluto at agmk dot net" <gcc-bugzilla at gcc dot gnu dot org>]

unsigned foo(unsigned long long x, unsigned long long y) { return x/y; }
float bar(double x, double y) { return x/y; }

$ g++ -Wall -O2 -c tmp.cpp
<no warnings>

why g++ doesn't warn users like similar to msvc ?
(warning: conversion from 'type1' to 'type2', possible loss of data)
