  91 # To do this, we must shutdown the currently running gdb and restart

  93 # the first gdb prompt, and the message we are looking for occurs

  95 # if it is empty, this confuses gdb with an empty argument that it
  96 # grumbles about (said grumbling currently being ignored in gdb_start).
  97 # **FIXME**

 100 # is apparently a limit on the length of a fully specified path to
 101 # the coremaker executable, at about 80 chars.  For this case, consider
 102 # it a pass, but note that the program name is bad.
