Hm, I may have spoken too soon here. If this port has always compiled successfully with -ansi, then indeed it may not be that handy to directly use the 'inline' keyword in system headers. I think most other system headers use '__inline', which is supported by both gcc and clang, even in ANSI mode. And if the compiler somehow does not support __inline, sys/cdefs.h can make sure all those keywords get removed.
