+// 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). |
