 188    This is because the code in this directory is used to build a
 189    library which will be linked with code in other directories to form
 190    programs.  We want to maintain a separate translation file for this
 191    directory however, rather than being forced to merge it with that
 192    of any program linked to libbfd.  This is a library, so it cannot
 193    depend on the catalog currently loaded.
 194
 195    In order to do this, we have to make sure that when we extract
 196    messages we use the BFD domain rather than the domain of the
 197    program that included the bfd library, (eg OBJDUMP).  Hence we use
 198    dgettext (PACKAGE, String) and define PACKAGE to be 'bfd'.
