debug or non-debug build?
& no, for a full release build, measuring the final executable size,
there's not much you can do with the compiler.
you can try to factor common portions out of your templates (eg: remove
template parameters where possible - if, for example, a member function of
a class template doesn't need all the template parameters - pull it out
into a standalone function template that takes fewer template parameters,
and call it from the member one)
