--- Comment #20 from Stas Sergeev <stsp at users dot sourceforge.net> --- Ah, makes sense, thank you. I was always wondering why under clang I need to do "-fdebug-macro" for that (which makes problems for gcc as being an unknown option). But "clang -g3 -fdebug-macro -E -Wp,-P - </dev/null" still doesn't produce anything interesting, so I wonder...
