The problem is more insidious that I first thought: the standard lib is
making an unqualified call to an internal detail function, and it's finding
my function of the same name via Argument Dependent Lookup.  Should now be
fixed (by renaming my version).

It relies entirely on implicit instantiation - there are no clever tricks
used with that class, so if there are linker problems then I'm stumped.
