I tried compiling the test battery on VC8 with precompiled headers
enabled (\Yc with test.hpp as the precompiled header) and encountered
similar problems. Eliminating the anonymous namespaces solves the
problem, and doesn't introduce any obvious new problems. Is there more
than a theoretical reason for the anonymous namespaces in the first
place? Is there any observed cases where not having anonymous
namespaces causes corruption to typeof?
