 The check in the header looks like this:
 {{{#if defined(__GLIBCXX__) || defined(__GLIBCPP__)}}}

 However, clang++ also defines (at least one of) these macros but doesn't
 offer the gcc demangle API, so anything that uses this header will fail to
 compile on clang (like boost/exception/detail/type_info.hpp - The fact
 that this header includes a detail header from another library is, in my
 opinion, a bug in itself that should be fixed).

 I "fixed" this by changing the line into:
 {{{#if !defined(__clang__) && (defined(__GLIBCXX__) ||
 defined(__GLIBCPP__))}}}

 I think this isn't a real fix. boost should use something like configure
 checks to see if {{{abi::__cxa_demangle}}} is actually usable.
