[cfe-dev] build error in git master

I installed this package through multiarch

linux-libc-dev:i386    :/usr/include/i386-linux-gnu/asm/unistd.h

and now I get this error:

  COMPILE:   clang_linux/asan-i386/i386: /opt/llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc
/opt/llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc:20:10: fatal error: 'new' file not found
#include <new>
         ^
1 error generated.



Searching for 'new' I get the following results:

$ mlocate new |grep /usr/include |grep new$
/usr/include/boost/tr1/tr1/new
/usr/include/c++/4.6/new
/usr/include/c++/4.7/new

I have libstdc++6-4.7-dev installed on my system which provides /usr/include/c++/4.7/new.
Trying to install libstdc++6-4.7-dev:i386 conflicts with the already installed version of the package for amd64.


If I change the previous line to 

#include <c++/4.7/new>

I get

  COMPILE:   clang_linux/asan-i386/i386: /opt/llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc
In file included from /opt/llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc:21:
/usr/include/c++/4.7/new:40:10: fatal error: 'bits/c++config.h' file not found
#include <bits/c++config.h>
         ^
1 error generated.


yet another search this time for 'bits/c++config.h' returns:

$ mlocate bits/c++config.h
/usr/include/c++/4.6/x86_64-linux-gnu/32/bits/c++config.h
/usr/include/c++/4.6/x86_64-linux-gnu/bits/c++config.h
/usr/include/c++/4.7/x86_64-linux-gnu/32/bits/c++config.h
/usr/include/c++/4.7/x86_64-linux-gnu/bits/c++config.h


I think this has to do with the debian way of installing header files (and libraries) in order to offer multiarch 
support.

The only workaround for me at the moment is to build without the changes introduced by commits r165096 and r165097 
which is something I am trying to avoid.

Any help would be appreciated.

Thanks,

Maroudas Manolis
