  85 # grumbles about (said grumbling currently being ignored in gdb_start).
  86 # **FIXME**

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