  28 # create a .core file, as opposed to just a .h file, GENESIS needs
  29 # symbol table data on the C runtime. And we can get that symbol
  30 # data only after the C runtime has been built. Therefore, even
  31 # though we ran GENESIS earlier, we couldn't get it to make a .core
  32 # file at that time; but we needed to run it earlier in order to
  33 # get to where we can write a .core file.)
