Rani Sharoni posted one possible implementation on http://tinyurl.com/459q 
(c.l.c++.m, 2002-07-11, topic 'is_abstract_class implementation!').

The implementation depends on border-case C++ feature (more in Rani's text). 
I compiled it sucessfully with Comeau online compiler.

It may be considered as addition to type_traits library, after the standard 
settles on it.

is_abstract_class<T> may be useful e.g. to enforce "don't derive from 
non-abstract classes" constraint.
