$cat gcc-wrap.c
#include <stdint.h>
#include <stdio.h>

int main()
{
        uint32_t a = 1 << 17;
        uint16_t b = a;
        printf("a: %u, b: %u\n", (unsigned)a, (unsigned)b);
        return 0;
}
$gcc -Wall -Wextra -Wconversion -pedantic gcc-wrap.c
no warrnings
$gcc --version
gcc (GCC) 4.1.1
for example:
$icc --version
iccbin (ICC) 9.1 20060706
$icc -Wall gcc-wrap.c 
gcc-wrap.c(7): remark #810: conversion from "uint32_t={unsigned int}" to
"uint16_t={unsigned short}" may lose significant bits
        uint16_t b = a;
                     ^

I think this has already been fixed on the trunk with the new -Wconversion
behaviors:
