+// Compile type discovery whether given type is abstract class or not.
+//
+// Requires DR 337 to be supported by compiler
+// (http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_active.html#337).
+//
+//
+// Believed (Jan 2004) to work on:
+// - GCC 3.4
+// - VC++ 7.1
+// - compilers with new EDG frontend (Intel C++ 7, Comeau 4.3.2)
+//
+// Doesn't work on:
+// - VC++6, VC++7.0 and less
+// - GCC 3.3.X and less
+// - Borland C++ 6 and less
+//
+//
+// History:
+// - Originally written by Rani Sharoni, see
+// http://groups.google.com/groups?selm=df893da6.0207110613.75b2fe90%40posting.google.com
+// At this time supported by EDG (Intel C++ 7, Comeau 4.3.2) and VC7.1.
+// - Adapted and added into Boost.Serialization library by Robert Ramey
+// (starting with submission #10).
+// - Jan 2004: GCC 3.4 fixed to suport DR337 (Giovanni Bajo).
+// - Jan 2004: modified to be part of Boost.TypeTraits (Pavel Vozenilek).
+// - Nov 2004: Christoph Ludwig found that the implementation did not work with
+// template types and gcc-3.4 or VC7.1, fix due to Christoph Ludwig
+// and John Maddock.
+// - Dec 2004: Added new config macro BOOST_NO_IS_ABSTRACT which causes the template
+// to degrade gracefully, rather than trash the compiler (John Maddock).
