It turns out that the clang warnings work differently in header files, specifically. In my test I just put the static inline function in a C file. clang does however not trigger -Wunused-function when the static inline function is included from a header. The code is the same after pre-processor expansion.

IMO these special cases just add to the confusion and my criticism of strange behavior, but I stand corrected on the actual behavior of the two compilers.
