After switching from Boost 1_57_0 to 1_58_0, I get various compile errors in pointer_traits.hpp, where it uses the macro BOOST_INTRUSIVE_HAS_STATIC_MEMBER_FUNC_SIGNATURE:

warning: declaration does not declare anything error: use of undeclared identifier 'check' error: 'U' does not refer to a value

This is with Xcode 4.6.3 and the Apple LLVM 4.2 compiler.

I haven't experienced that myself, so this is only a wild guess.

However -- Apple defines a 'check' macro in some system header that notoriously wreaks havoc on software that innocently uses the name 'check' for a perfectly legal data member.

Try '#undef check' before your #include for Boost sources?

Yes, that works, thanks. Apparently it's coming from AssertMacros.h. It also works to say #define __ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES 0 in a prefix header.
