Scratch that. While -Wfloat-conversion does check fine for
int into double, it also does the "whole lot less useful, even
though technically accurate" double into float message.

Like

float f = 3.1;

warning: conversion to ‘float’ alters ‘double’ constant value
[-Wfloat-conversion]

I'll proceed with -Wfloat-conversion, but I'll be stripping out
(fgrep -v) these unwanted warnings.
