[boost] filesystem

For some reason I get following error when compiling the filesystem library 
with VisualAge 6.

xlc-C++-action 
/home/tk/cvstop/DO/libs/filesystem/build/bin/libfs.a/vacpp/debug/runtime-link-dynamic/operations_posix_windows.o
"/home/tk/boost/boost/boost/operators.hpp", line 143.18: 1540-0403 (S) 
"boost::operator!=(const directory_iterator &, const directory_iterator &)" 
is already defined.
"/home/tk/boost/boost/boost/operators.hpp", line 142.18: 1540-0425 (I) 
"operator!=" is defined on line 142 of 
"/home/tk/boost/boost/boost/operators.hpp".
"/home/tk/boost/boost/boost/operators.hpp", line 795.2: 1540-0700 (I) The 
previous message was produced while processing "struct 
boost::equality_comparable2<boost::filesystem::directory_iterator,boost::filesystem::directory_iterator,boost::detail::empty_base>".
"../src/operations_posix_windows.cpp", line 142.48: 1540-0274 (S) The name 
lookup for "end_itr" did not find a declaration.

The problem disappears if I modify line 82 in filesystem/operations.hpp from

      public boost::equality_comparable< directory_iterator >,

into 

      public boost::equality_comparable1< directory_iterator >,

I see no reason why the former resolved to equality_comparable2 but 
apparantly it does. So what's the best way to patch this ?
Modify the filesystem library to use "equality_comparable1" or find some way 
to make equality_comparable automatically resolve to equality_comparable1 ?
