It depends on what you mean by conformant. Algorithms like
for_each do not require these typedefs. Adapters like not1
do. If you need to adapt an arbitrary function object,
you're safer using !boost::bind<bool>(pred) instead of
std::not1. This will also work with function pointers. (Which
std::not1 doesn't handle)

If only I could! Using Boost throughout would be far-and-away the best
solution, trouble is at the point of definition of if_all( ) I don't have, and
can't make, Boost available, whereas at the point of use I have.

Thanks for all your help.
