RFA: libstdc++ PATCH to initializer_list to #error in C++98 mode
- From: Jason Merrill <jason at redhat dot com>

- Subject: RFA: libstdc++ PATCH to initializer_list to #error in C++98 mode
I have on occasion been confused by <initializer_list> silently becoming
empty in C++98 mode. OK for trunk?

commit 3d7ac3e4d8bb54921eb3e1f70b1a42a165ba4f5b
Author: Jason Merrill <jason@redhat.com>

* libsupc++/initializer_list: Copy C++0x #error from
