   This is because the code in this directory is used to build a
   library which will be linked with code in other directories to form
   programs.  We want to maintain a separate translation file for this
   directory however, rather than being forced to merge it with that
   of any program linked to libbfd.  This is a library, so it cannot
   depend on the catalog currently loaded.

   In order to do this, we have to make sure that when we extract
   messages we use the BFD domain rather than the domain of the
   program that included the bfd library, (eg OBJDUMP).  Hence we use
   dgettext (PACKAGE, String) and define PACKAGE to be 'bfd'.
