| ?? No comprende

as a library witer you want to support as many platforms as possible--you want 
the code to wok with vc6 and borland,
if possible. Hence you have to #ifdef every ADL lookup point in your code.

I think some compilers do get ADL when the function is seen *before* the ADL 
lookup point, but not between
the lookup point and the intantiation. I would have to run a new test to be 
sure of the compiler conformity, though.
