Not fixed in clang 2.8, I hope I'm not in error reopening this:

Test case:
$ cat test.c 
#include <stdio.h>
#include <wchar.h>

int main(int argc, char *argv[])
{
    wchar_t foo;
    foo = L't';
    printf("%lc", foo);
    printf("%lc", (wint_t)foo);
}

$ gcc test.c && ./a.out
tt

$ clang test.c && ./a.out
test.c:9:12: warning: conversion specifies type 'int' but the argument has type
'wint_t' (aka 'unsigned int') [-Wformat]
        printf("%lc", (wint_t)foo);
                ~~^   ~~~~~~~~~~~
                %u
1 warning generated.
tt

$ clang --version
clang version 2.8 (branches/release_28)
Target: x86_64-unknown-linux-gnu
Thread model: posix


This compiled without warnings in clang 2.7.
