- * directives. Suppress the warning in clang as well by using "unused"
- * function attribute, which is redundant but not harmful for gcc.
- * Prefer gnu_inline, so that extern inline functions do not emit an
- * externally visible function. This makes extern inline behave as per gnu89
- * semantics rather than c99. This prevents multiple symbol definition errors
- * of extern inline functions at link time.
- * A lot of inline functions can cause havoc with function tracing.
