Boost Testing : |

I looked at this. I used the name BOOST_IS_ABSTRACT(T) to permit a user of
the serialization library to flag a class as abstract in the absense of
support from the compiler.
However, that is different than the usage you gave it. I looked at this
some more and
decided to do the following:
a) In the serialization library I changed BOOST_IS_ABSTRACT(T) to
BOOST_SERIALIZATION_ASSUME_ABSTRACT(T)
b) changed a boost::serializaton::is_abstract to BOOST_IS_ABSTRACT(T)
I tested this on my msvc 7.1 system ans well as msvc 9.0. With msvc 7.1
I had no problem. With vc 9.0 I had some problems.
a) Looking through the code in intrinsics.hpp it looks like at some point
BOOST_IS_ABSTRACT(T) is defined so that is resolves to
is_polymorphic. If my understanding of this is correct, its really a bad
idea.
Attached is what I want to use in the serialization library - but it won't
build on msvc 9.0. I bails at
// required by smart_cast for compilers not implementing
// partial template specialization
BOOST_BROKEN_COMPILER_TYPE_TRAITS_SPECIALIZATION(
boost::archive::detail::basic_iarchive
)
Which sort of mystifies me.
