CXXSTD=c++11

[Just a few notes related to some points in the exchange.]

powerpc and powerpc64 are in the same boat as mips and sparc for clang's 
overall status: clang does not work yet, independent of any FreeBSD issues that 
might exist if clang's code generation was okay. (See 
https://llvm.org/bugs/show_bug.cgi?id=25780 and what it "depends on".)

I've been able to buildworld using WITH_LIB32= via 
powerpc64-xtoolchain-gcc/powerpc64-gcc with the libcxxrt _Static_assert 
disabled but what was built has never worked because of some of the code in the 
crtbeginS.o produced. (See 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206123 .)

powerpc64-xtoolchain-gcc/powerpc64-gcc as it is currently built when used on a 
powerpc64 (self hosting "cross builds" for buildworld) historically looks in 
and prefers /usr/local/include/ include files so I first rename files that 
caused me problems, for example:

> # ls /usr/local/include/renamed_*
> /usr/local/include/renamed_dwarf.h/usr/local/include/renamed_iconv.h  
> /usr/local/include/renamed_libdwarf.h

I do not know if the -isystem change(s) will improve this to prefer the likes 
of (in my context) 
/usr/obj/xtoolchain/powerpc.powerpc64/usr/src/tmp/usr/include/c++/v1 and/or 
/usr/obj/xtoolchain/powerpc.powerpc64/usr/src/tmp/usr/include or not. It is too 
bad that powerpc64-gcc automatically looks in /usr/local/include .

Direct use of the live-system's /usr/include/c++/v1 area would be the wrong 
place if that code had updates. As I understand things, ${WORLDTMP} use is 
appropriate in forming the include directory paths (in my context: 
/usr/obj/xtoolchain/powerpc.powerpc64/usr/src/tmp prefixes).

boost/asio/ip/resolver_query_base.hpp:96:3: warning: all paths through this function will call itself

[Willem Jan Withagen]

Hi Dimitry (or others),

Any suggestions why I'm getting this warning/error in the ceph code:

In file included from log/Log.cc:12:
In file included from /usr/local/include/boost/asio.hpp:63:
In file included from 
/usr/local/include/boost/asio/ip/basic_resolver.hpp:24:

/usr/local/include/boost/asio/ip/resolver_query_base.hpp:96:3: warning: 
all paths through this function will call

  itself [-Winfinite-recursion]

Could be a boost error, but I have not seen any upgrades to a newer version.
