Then why not derive it from the used namespace? Is that because you do not necessarily use only a single namespace per file which could make creating the macro name tricky? Or because in order to know the namespace, the compilation process has to start, which happens after preprocessor "applies" the header guards, which in turn would make some kind of double compilation necessary? Good old C++ feels somewhat clumsy in this regard compared to how C# or java handle the inclusion of other files.

@null I forgot that part - I do that when I use namespaces, which I generally do even when writing a regular program as opposed to a library.
