  28         # able to interact with these variables with some care (they have
  29         # to know how to interpret them according to their real type,
  30         # since gdb doesn't know the type), but (b) users should be able
  31         # to detect that gdb does not know the type, rather than just
  32         # being told they are ints or functions returning int like old
  33         # versions of gdb used to do.

  38         # better, but for now xfail these tests.  Irix5, even though
  39         # it is ELF, counts as "ecoff" because gcc puts out a .mdebug
  40         # section even without -g.  Personally, I think that is pretty
  41         # dubious, but maybe dbx requires it.
