So, you're looking for the stacktrace and frame classes to not provide
implementations of those member functions which rely on windows.h?

I assume you then want an additional header file e.g.
"stacktrace_extra.hpp" which provides implementations for those?

If you do want this, one technique I've used in AFIO is for the public
class to be mostly virtual member functions so header only includes
don't drag in tons of implementation. Filing system operations are much
heavier than Stacktrace's though, for AFIO a virtual function call is
immaterial. I suppose a performance caring Stacktrace user would simply
include the kitchen sink and rely on "override final" to eliminate the

Is this what you are looking for?
