VC6 is one of the few implementations that occasionally fails to build - and
then only if the template was implicitly instantiated with two or more
identical sets of types that differ only in default parameter values.  VC7,
unfortunately, lost this feature, and will compile & link with no error (as
did all versions of GCC I've tried this on).
