[SOLVED] What's broken with clang++ and string.h?

Question

Not sure when this started:
$ cat foo.cpp
#include <cstring>
$ clang++ -c foo.cpp # Works fine
$ clang++ -O2 -c foo.cpp
In file included from foo.cpp:1:
In file included from /usr/bin/../lib64/gcc/x86_64-unknown-linux-gnu/4.9.2/../../../../include/c++/4.9.2/cstring:42:

/usr/include/string.h:82:24: error: expected unqualified-id

The upstream glibc-2.20 branch has one out of a pair of patches backported.   I will fix it both upstream and here today.
