[Bug c++/27979] New: conversion check confused by enum bitfields

[tbm at cyrius dot com]

I think the following "invalid conversion" error, which is believe is wrong. 
When I remove the bitfield, the program compile fine.  In any case, the error
message isn't really optimal. :)


(sid)4502:[EMAIL PROTECTED]: ~/src] cat test.cpp
class Ast
{
    enum AstKind { };
    const AstKind kind : 8;
    void foo(AstKind k) { }
    void bar(void) { foo(kind); }
};
