                                 WARNING

         This working version is believed to be stable, but
         we have not run our full regression-test suite.

Summary:

      The most important and noticable changes in 110.47 concern
      preliminary implementations of the NLFFI foreign-function
      interface under Mac OS X (PowerPC) and Win32 (x86).  There are
      also a number of important bug fixes.

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

Details:

NLFFI:
------

   - preliminary support for Mac OS X added
   - preliminary support for Win32 added
     (untested;
      currently can only interface with C functions using the stdcall
      calling conventions)
   - function arguments that are C unions are now handled
   - various minor bug fixes to ml-nlffigen
   - preliminary documentation for nlffi and ml-nlffigen
     (currently only describes the output of ml-nlffigen;
      see src/ml-nlffi-lib/Doc/manual/nlffi.tex)

Compilation Manager:
--------------------

   - made "make" commend in CM's "make" tool configurable
   - added option (default: on) for passing the name of the SML/NJ's  
"bin"
     directory to "make";
     This can be used by the Makefile to, e.g., pick the "right" version
      of ml-nlffigen.

Basis:
------

   - Changed the implementation of structure Unix so that the
     same stream is returned every time one of the
     {text,bin}{In,Out}streamOf functions is invoked on the
     same proc. (NOTE: This is not what the spec says, so it will
     probably change again. Don't rely on it!)

Windows port:
-------------

   - bug fixes:
      * NULL test in gmtime and localtime
      * toSeconds -> toMilliseconds in win32-process.sml (Basis  
implementation)

Installer:
----------

   - eliminated some shell syntax not understood by /bin/sh under Solaris

Compiler internals:
-------------------

   - redesigned c-calls interface
   - c-calls implementation for ppc-macosx added
   - low-level support for choosing C calling conventions by twiddling  
the
     type of of the rawccall primop  (see  
src/compiler/Semant/types/cproto.sml
     for details)
   - use paramAlloc to report c-calls with too many arguments
     (for PPC version where parameter area is pre-allocated)
   - added ccall_maxargspace to machspec (to implement the above)

MLRISC:
-------

   - Added these instructions to the PowerPC architecture:
     LWARX, STWCX, LBZU(X), LHZU(X), LWZU(X), STWU(X), STFDU, STFSU, etc.
     (Instruction encodings not added yet, though.)
   - loop-structure.sml has been rewritten
