[boost] [type traits] is_abstract_class submission

From: Pavel Vozenilek (pavel_vozenilek_at_[hidden])
Date: 2004-01-11 07:43:59

This is submission of is_abstract_class<> type trait
into Boost.TypeTraits.

Reasons for submission:
  - it will offload Serialization library a bit (it is currently here)
  - Giovanni Bajo added support for it (for DR 337) into GCC 3.4

The code and documentation is TypeTraits compatible.
It was tested with Intel 7.0 and 8.0.

The idea comes from Rani Sharoni,
Robert Ramey wrote current implementaton.

____________________________________________________
Changes needed in Boost:

1. file is_abstract_class.hpp is put into
   boost/type_traits/

2. boost/type_traits.hpp, following line is added
   at the end:

#include "boost/type_traits/is_abstract_class.hpp"

3. libs/type_traits/index.html:

   Table "Secondary Type Categorisation" will be appended
   with text (no fancy formatting here):

<tr>
  <td>
      ::boost::is_abstract_class<T>::value
  </td>

  <td>
      Evaluates true only if T is abstract class.
  </td>

  <td>
      10.4
  </td>

  <td>
      Compiler must support DR337 (as Jan 2004: GCC 3.4,
      VC++ 7.1, Intel C++ 7, Comeau 4.3.2).
  </td>
</tr>

4. file is_abstract_class_test.cpp is put into
   libs/type_traits/

5. Jamfile here gets updated.
