  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>

  /*
   * This code implements the MD4 message-digest algorithm.
   * The algorithm is due to Ron Rivest.  This code was
   * written by Colin Plumb in 1993, no copyright is claimed.
   * This code is in the public domain; do with it what you wish.
   * Todd C. Miller modified the MD5 code to do MD4 based on RFC 1186.
   *
   * Equivalent code is available from RSA Data Security, Inc.
   * This code has been tested against that, and is equivalent,
   * except that you don't need to include two pages of legalese
   * with every copy.
