Just wondering, are these changes for the sake of documentation, or are they really needed (do you see problems without them)? In my experience with clang, it always defines both __clang__ and __GNUC__ so changes like this don't change behavior. I definitely have no objection to adding them; I'm curious if there's something going on here I'm not familiar with. $ clang -x c /dev/null -dM -E | grep -i gnu #define __GNUC_MINOR__ 2 #define __GNUC_PATCHLEVEL__ 1 #define __GNUC_STDC_INLINE__ 1 #define __GNUC__ 4 #define __gnu_linux__ 1
