|
| +// 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).
