      25     Well, some generic common stuff is done here too, like including
      26     ansidecl.h.  That's because the .h files in bfd/hosts files I'm
      27     trying to replace often did that.  If it can be dropped from this
      28     file (check in a non-ANSI environment!), it should be.  */
