Robert, I'm just about done. I'm unable to test on cw-8.3 at the moment because the test library seems to be broken there. As for cw-9.4, the export tests never worked there, presumably for the same reason I'm seeing: when a class template static member is used only as the result of another template instantiation, it may never get initialized. As a result, base/derived relationships are not getting registered. Aside from that, all export tests seem to be passing, including release mode tests on vc-8.0. I was able to clean up a *lot* of messy code. Would you like me to: 0. Check my code in on the trunk 1. Check my code in on a branch so you can review it 2. Post patches (not recommended; the diffs are large) 3. Something else? -- Dave Abrahams Boost Consulting www.boost-consulting.com
