Summary:
	
	o Port to ppc Linux (thanks to Carl Pulley).

        o support for fsqrt, fptan, fcos, fsin.

	o Several CM and CMB changes.
 
 	o Some critical bug fixes

 		------------------------------------

Bug fixes:
	o 1514.  sockets c-library broken 
	o 1582.  SysErr exception connecting to socket


Back ends:

 x86:

   All back ends now directly generate the sqrt instruction, and the Intel 
   x86 also generate the trig instructions to implement sine, cosine, and
   tangent.

   The ICFP00, PCLubIN entry shows a significant improvement as a result
   (most of it coming from fsqrt).

CM (compilation manager):

  Changes to scripts:
      * "ml-build" for generating standalone programs
      * "ml-makedepend" (new!) for generating Makefile dependencies
        (not generally required but some project might want them)
      * "sml" - the main driver script for running SML/NJ.
     + All these scripts now accept more CM-related command-line options.
     + ml-build is faster and cleverer in avoiding unnecessary work.

  Type of CM.mk_standalone has changed.

  All user-visible changes to CM (including the above-mentioned scripts)
    are documented in the CM manual.  Some errors and omissions have been
    corrected as well.

  Bug fixes to CM's internals (e.g., missing or repeated error messages).

  Pickling/Unpickling improvements result in faster autoloading and
    reduce resident memory size.

CMB (bootstrap compiler):

  Conditional compilation within the "init library".
    (One can now use "ifdef" and "ifndef" guards in init.cmi.
     This is documented in the long comment at the beginning of
     that file (src/system/smlnj/init/init.cmi).)


Basis Library:

  Added SMLofNJ.SysInfo.getHeapSuffix (for use by "ml-build").
