Summary:

      This is a bugfix release.  Its main purpose is to solve
      a another showstopper problem introduced into the x86 c-calls
      implementation which is used by NLFFI.  It also fixes a
      problem with the signal masking/unmasking code.

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

Details:

Basis:
------

   - Fixed the signal masking code to properly nest mask/unmask
     operations on a per-signal basis.

MLRISC:
-------

   - fixed problem in x86/c-calls that caused NLFFI to generate bogus  
code
   - bug fix in udgraph.sml
   - The IBM/MacOS syntax switch on PPC was incorrectly swapped. Fixed.

Runtime:
--------

   - heap image magic number updated
     (causes a graceful exit rather than a crash when an outdated
      heap image is being loaded)
   - Cygwin support

Libraries:
----------

   - added some exports to src/compiler/core.cm
   - added a ptreql functon to structure InlineT (exported from
     $smlnj/init/init.cmi)


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

   - falls back to copying when renaming of files fails
     (usually this happens when source and destination are in different
      file systems)
