The [[ https://clang.llvm.org/docs/AttributeReference.html#gnu-inline | documentation ]] seems to imply that either `__GNUC_GNU_INLINE__` or `__GNUC_STDC_INLINE__` will be defined if the `__gnu_inline__` attribute is supported, so that's what I am now checking for. Let me know if you had something else in mind.
