  Stop using non-portable <sys/cdefs.h> For portability, we should not rely on the __BEGIN_DECLS, __END_DECLS and __P to be predefined somewhere. For __P, we just remove its usage as we do not support pre-ANSI-C compilers. [guillem@hadrons.org: - Separate extern declarations with newlines. - Slightly reword commit message. ] Signed-off-by: Guillem Jover <guillem@hadrons.org>
