 So I get:

 /home/hunold/packages/boost/boost/graph/adjacency_list.hpp:22:35: error:
 backward/hash_set: No such file or directory
 In file included from
 /home/hunold/packages/boost/boost/graph/detail/adjacency_list.hpp:31,
                  from
 /home/hunold/packages/boost/boost/graph/adjacency_list.hpp:309,

 when compiling with gcc-4.2 GLIBCXX

 My gcc-4.2 on Hardy has _much_ higher version than the SuSE compiler.
 I suggest either taking a _much_ higher version number or even better
 a check for compiler major and minor to _really_ fix the issue

 Please note that changes to boost/config/stdlib/libstdcpp3.hpp will _not_
 trigger the regression tests because the configuration files are selected
 via
 #  define BOOST_STDLIB_CONFIG "boost/config/stdlib/libstdcpp3.hpp"
 and so later #include BOOST_STDLIB_CONFIG. So please don't wonder if all
 tests remain green...
