compiler, clang: suppress warning for unused static inline functions
GCC explicitly does not warn for unused static inline functions for
-Wunused-function. The manual states:
Warn whenever a static function is declared but not defined or
a non-inline static function is unused.
Clang does warn for static inline functions that are unused.
It turns out that suppressing the warnings avoids potentially complex
#ifdef directives, which also reduces LOC.
Suppress the warning for clang.
