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

I just put that one there last week ;-)

libs/dynamic_bitset/example/timing_tests.cpp

You can add the iostreams library to your list. I copied the test from dynamic bitset, and am responsible for sticking it in Boost.Range.

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

I think last time it was suggested suggested to have a config macro for 'old' iostreams, John Maddock's view was that BOOST_NO_STD_LOCALE should be sufficient. However, this would incorrectly select old iostreams for Metrowerks with a dynamic runtime and Intel 7.1 with Dinkumware, and perhaps others. So I'd be in favor of having a config macro which the various libraries you mention could share. Regarding Cray X1 C++, how much of Boost does it compile? Jonathan
