    36  dnl  We maintain lists of stuff to append in load_eip and darwin_bd.  The
    37  dnl  `index' stuff is needed to suppress repeated definitions.  To avoid
    38  dnl  getting fooled by "var" and "var1", we add 'bol ' (the end of
    39  dnl  'indirect_symbol') at the beginning and and a newline at the end.  This
    40  dnl  might be a bit fragile.
