#1398 It's actually not possible to use a define inside a macro (see https://stackoverflow.com/questions/7246512/ifdef-inside-a-macro). I therefore had to duplicate the macro for the clang and not clang cases... (using a middleman macro didn't work as the warnings about macro recursion popped up - the very same for which I had to disambiguate clang and gcc in the first place in the macro...)
