implicit cast from unsigned long to unsigned int gives no warning with -Wall (64 bits arch)

["Manuel López-Ibáñez" <lopezibanez@xxxxxxxxx>]

>From GCC 4.3 onwards you can use -Wconversion.

test.c: In function 'main':
test.c:16: warning: conversion to 'unsigned int' from 'long unsigned
int' may alter its value

Previous versions have a Wconversion option but it won't do what you
want even if you think it does. Read more here:
