Add a paragraph about an optimization bug in SGI compilers which affects 

complex objects, and explain how to build so that Objects/complexobject.c
is compiled without optimization.

@ -374,6 +374,13 @@ SGI: SGI's standard "make" utility (/bin/make or /usr/bin/make)
you set the first line of the Makefile to #!/usr/sbin/smake
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
and type NMAKE. Threading and sockets are supported by default
