No, C4675 is the opposite of what Dave wants. Earlier MSVC didn't support
ADL at all, and MSVC 7.1 is now issuing the warning for every place ADL
kicks in since this may alter the behavior of existing code. Dave wants a
warning when ADL could have kicked in but didn't. Sounds like a neat plan to
solicit _many_ user complaints. ;-)
