/* Do system-dependent stuff, mainly driven by autoconf-detected info.

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