I note that the test of ztest_max_digits10 and zztest_max_digits10 in

http://www.boost.org/development/tests/trunk/developer/math.html  

both fail  for these platforms.

ztest_max_digits10 tests of native std::numeric_limits<>::max_digits10 is supported.
zztest_max_digits10 test if BOOST_NO_NUMERIC_LIMITS_LOWEST is a proxy to signal support.

where using std::numeric_limits<>::max_digits10 should be possible using
BOOST_NO_NUMERIC_LIMITS_LOWEST as a proxy 

for Clang the messages are

In file included from ../libs/math/test/zztest_max_digits10.cpp:27:
In file included from ../boost/config.hpp:40:
../boost/config/select_stdlib_config.hpp:18:12: fatal error: 'cstddef' file not found

or for Cray CC-1353 crayc++: INTERNAL File = /opt/gcc/4.4.4/snos/include/g++/bits/move.h, Line = 34
  CIF Error

                    ^
This appears to be a problem in the config - a missing include.

Suggestions?
