Joseph S. Myers <jsm28 at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Joseph S. Myers <jsm28 at gcc dot gnu.org> --- GCC accepts C++ raw strings as an extension in -std=gnu* modes for C. Use standards conformance modes if you want it rejected for C (and, in general, please try conformance modes, -pedantic etc. yourself to establish whether an extension is involved before reporting a bug simply because of behaving differently to another compiler).
