  	smake will be invoked by make (likewise for GNU make).
  
+ 	There is a bug in the SGI compiler's optimization that causes a
+ 	bus error in PyComplex_ImagAsDouble(); this has been reported to
+ 	be triggered when importing Numeric Python and may be caused at
+ 	other times.  The work-around is to build Python, delete the
+ 	Objects/complexobject.o file, and then recompile without
+ 	optimization (use "make OPT=").

  OS/2:   If you are running Warp3 or Warp4 and have IBM's VisualAge C/C++
          compiler installed, just change into the pc\os2vacpp directory
