That's what > standard include guards do. Yeah, the proposed solution isn't good for guarding against recursive inclusion as it stops the same header from being included more than once (which easily happens, and is not an error nor even bad design). There is a way to detect recursive inclusion, but you need additional defines to do that. Something like: #ifdef A_H_RECURSION_GUARD #error "a.h is being recursively included"
