Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

  'comint-interrupt-subjob' does never worked for
  Solaris 9 and, _after_ installing all Solaris patches,
  is broken now for our Solaris 8 boxes too. 

  *Before*
  applying the patches 'C-c C-c' works fine
  on the solaris 8 boxes! 

  As far as I can
  see, 'comint-interrupt-subjob' is still 
  working on fully patched Solaris 2.7 and 
  Solaris 2.6 boxes (with the same configuration), but
  broken for sol8 and 9 independently
  from the version (20.7/21.2) or the
  op-sys-version (2.7,8,9) it's build for
  (if it is running anyhow...).
  
  so I first guessed, that this is an op-sys 
  problem -- but the 'comint-interrupt-subjob'
  function in 'XEmacs' remains intact!

  This broken 'comint-interrupt-subjob' 
  affects the normal shell
  (M-x shell) and other modes running subjobs,
  like IDLwave mode, Gnu-R or Octave...

  -- and this is quite annoying.

  any hint -- any hope?
