[boost] Patch for BOOST_OLD_IOSTREAMS detection

Hi,

Several places in Boost try to detect BOOST_OLD_IOSTREAMS using the 
following ifdefs:

// support for pre 3.0 libstdc++ - thanks Phil Edwards!
#if defined (__STL_CONFIG_H) && !defined (__STL_USE_NEW_IOSTREAMS)
# define BOOST_OLD_IOSTREAMS
#endif

This incorrectly defines BOOST_OLD_IOSTREAMS for the Cray X1 C++ 
compiler. Could this be changed to include an
&& !defined(__crayx1) or something similar as in:

#if defined (__STL_CONFIG_H) && !defined (__STL_USE_NEW_IOSTREAMS) && 
!defined(__crayx1)
# define BOOST_OLD_IOSTREAMS
#endif

Three offending files are:

boost/dynamic_bitset/config.hpp
boost/range/iterator_range.hpp
libs/dynamic_bitset/example/timing_tests.cpp

Maybe it would be best to move this to the global config file?

Best regards

Matthias
