I have just been reading  n1792 "A modest  proposal fixing ADL". In it Herb
Sutter states that only two compilers of those tried VC8 and  Com4.3.3 do ADL
correctly, so maybe this is behind your problems. Having said that I have put my
types and their operations in the same namespace as recommended in the paper
(though I havent practisd the 'defensive programming' mentioned there),  and I'm
still getting errors.
