Uh, wait...
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 I find:
&& !BOOST_WORKAROUND(__EDG_VERSION__, <= 238) && 0^ Where did this come from?--------------------------^
Sorry that was what I added to find the problem originally, and forgot to remove when I realized what was going on and sent the e-mail. I apologize for the confusion this caused. The real line is:
&& !BOOST_WORKAROUND(__EDG_VERSION__, <= 238)
This is line 29 of boost/type_traits/is_base_and_derived.hpp
And furthermore, the code inside #if !BOOST_WORKAROUND(...) is all NON-workaround code, so the workaround _is_ being used for all versions 238 and lower.
The version just after that #if is the one that does not compile with KCC 4.0 . I interpreted this in the manner that this non-workaround version does not work, and that we need the workaround version after the #else . Do I see this incorrectly?
