Comment 18 for bug 885280

This patch:

http://gcc.gnu.org/ml/gcc-patches/2010-09/msg01459.html

fixes the bug, but caused:

FAIL: g++.dg/conversion/op5.C (test for errors, line 18)
FAIL: g++.dg/conversion/op5.C (test for excess errors)

Now, we get

[hjl@gnu-6 gcc]$ ./xgcc -B./ -S -O /export/gnu/import/git/gcc/gcc/testsuite/g++.dg/conversion/op5.C -ansi -pedantic-errors
/export/gnu/import/git/gcc/gcc/testsuite/g++.dg/conversion/op5.C: In function \u2018void foo(const B&)\u2019:
/export/gnu/import/git/gcc/gcc/testsuite/g++.dg/conversion/op5.C:18:15: error: conversion from \u2018const B\u2019 to non-scalar type \u2018A\u2019 requested
[hjl@gnu-6 gcc]$

"const" is missing.
