It's been in the MinGW bug tracker for years, although now closed as "out of
date"

It's not possible to fix in GCC without extraordinary effort for a single
target, which is not going to happen. If a given target wants to support C++11
features then it needs to provide the necessary C99 features. This is not a GCC
issue.

Fine. How about some ACTUALLY DOES SOMETHING USEFUL instead of quibbling over
the particular wording I used in a bugzilla comment?
