   1 # This file is a shell script that overrides some of the tools and
   2 # flags used on a host specific basis.

   4 # Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
   5 # binutils directories (at least), the index to it is also shared.
   6 # This is that index.  Each configure.in file should source this file
   7 # in its per-host part.

  12 #  HOST_64BIT_TYPE      host 64 bit type
