Test program (Create a New Attachment is not working for me today):

const int  i = -1;

unsigned int slip_one_by()
{
    return i;
}

unsigned int caught_me()
{
    return -1;
}

$ gcc -c unsigned_return.c -Wconversion
unsigned_return.c: In function `caught_me':
unsigned_return.c:10: warning: negative integer implicitly converted to
unsigned type

Expected a warning for line 5, too.
