Dear Boosters,

Unfortunately we could not test 1.30 extensively and thus found a
problem with the current Boost sources just after a release.

When trying to compile the filesystem library with KAI C++ we encounter
a problem in
boost/type_traits/is_base_and_derived.hpp

It seems that the workaround is needed also for KCC, since otherwise we
get the error message

line 126: error:
           expression must have (pointer-to-) function type
       BOOST_STATIC_CONSTANT(bool, value =

Looking at the #if before this version I find:

&& !BOOST_WORKAROUND(__EDG_VERSION__, <= 238) && 0
                              // The EDG version number is a lower
estimate.
                              // It is not currently known which EDG
version
                              // exactly fixes the problem.

KAI C++ version 4.0f has an __EDG_VERSION__ of 243 but this still
fails. Can 238 here be changed at least to 243?

Best regards,

Matthias Troyer
