dg-error vs. i18n?

[Dave Korn <dave.korn.cygwin@googlemail.com>]

    Hi everyone,

  Sorry for posting a dumb question, but it's not my strongest area: now that
cygwin is handling i18n and unicode and "all that stuff", I started seeing a
whole slew of test failures, e.g.:

> FAIL: g++.dg/debug/pr22514.C  (test for errors, line 12)
> FAIL: g++.dg/debug/pr22514.C (test for excess errors)
> Excess errors:
> /gnu/gcc/releases/4.3.4-2/gcc4-4.3.4-2/src/gcc-4.3.4/gcc/testsuite/g++.dg/debug/pr22514.C:12:
> error: expected unqualified-id before ‘}’ token

  The reason appears to be because the testcase has single-quotes in the regex
pattern:

>> $ cat g++.dg/debug/pr22514.C -n
>>      1  /* { dg-do compile } */
>>      2  namespace s
>>      3  {
>>      4    template <int> struct _List_base
>>      5    {
>>      6       int _M_impl;
>>      7    };
>>      8    template<int i> struct list : _List_base<i>
>>      9    {
>>     10      using _List_base<i>::_M_impl;
>>     11    }
>>     12  }  /* { dg-error "expected unqualified-id before '\}'" } */
>>     13  s::list<1> OutputModuleListType;

... where the actual compiler outputs those fancy left- and right-facing
quotes.  It will probably go away if I set LC_ALL=c or something like that,
but is dg-error meant to be insensitive to this kind of transformation, or
would it be best if dg-error test patterns didn't include any kind of quote
chars that might get i14ed?

    cheers,
      DaveK
