I'm still not certain why this is different, but this test case used
to pass on Windows when run from vanilla cmd.exe, and now it's stopped
(though it does run fine from a VS 2010 command prompt).  The problem
is a string of errors dealing with auto:

Command 0 Stderr:
error: 'error' diagnostics seen but not expected:
  Line 414: 'auto' not allowed in function return type
  Line 414: expected ';' at end of declaration list
  Line 414: 'auto' not allowed in function return type
  Line 414: expected ';' at end of declaration list
  Line 414: expected parameter declarator
  Line 414: expected ')'
  Line 414: '_Fn' cannot be the name of a parameter
  Line 414: expected ';' at end of declaration list
  Line 197: use of undeclared identifier 'static_assert'; did you mean 'static_c

  Line 214: use of undeclared identifier 'static_assert'; did you mean 'static_c

  Line 238: expected parameter declarator
  Line 238: expected ')'
  Line 442: function definition does not declare parameters
  Line 488: no viable conversion from 'int' to 'std::exception_ptr'
  Line 527: unknown type name 'nullptr_t'
  Line 532: unknown type name 'nullptr_t'
error: 'note' diagnostics seen but not expected:
  Line 414: to match this '('
  Line 237: to match this '('
  Line 450: candidate constructor not viable: no known conversion from 'int' to
'const std::exception_ptr &' for 1st argument
19 errors generated.

So I do agree that the -std=c++11 change isn't a good fix (I'll back
it out), but I'm stumped as to why this has suddenly stopped working
when it was previously fine.
