3004	test_dll_exported fails	marvin.sielenkemper@…	Robert Ramey	"Built with msvc-8.0.

The failure message is:
d:\boost\boost.build\libs\serialization\test\test_tools.hpp(183): unregistered void cast in function 'int __cdecl main(int,char *[])'
1 error detected.

I found and fixed this problem first with our own test suite.

Problem:
The lib allows multiple instances of the extended_type_info to represent the same type. This seems to be ok in most cases.
But in the void cast code this breaks and reports a missing cast where there is one present: the equality (or order in that case) is too fine.
I added the proper weaker equality and search the cast list again using that if the first search failed.

Assembling the patch for this ticket, I noticed that there already is a unit test for the kind of DLL exported stuff we use. But it was not executed. So I fixed that, ran the test on the original lib and it failed. With my patch it succeeds again.
