                                WARNING

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

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

Summary:

	This release is primarily a bugfix release.

installer:
      - Eliminated any mention of lexgen.  (Lexgen was an early precursor
	to ml-ulex.)

command-line tools:
      - Fixed typo in ml-build script that prevented library anchors
	from being registered.

SML Basis Library:
      - Fixed a number of inconsistencies between the Posix.TTY structure
	and the Basis specification.  Thanks to Adam Chilpala.

CM:
      - Fixed bug in CM's parallel make facility that failed to have
	the master re-link modules after letting slaves compile them.

MLRISC:
      - x86MCEmitter crashed when the immediate operand to MOVB was outside
	of the range -128 ... 127.   Only the low order 8 bits of the
	immediate operand are now significant.

      - Added preliminary support in MLRISC for Staged Allocation, a technique
	for specifying calling conventions.  See

		http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html

	Initially, this mechanism is being used to generate C calls for the
	AMD64.

      - Fixed bogus operand sizes in AMD64 instruction spilling.

runtime:
      - Fixed a problem with files that have very large numbers of literals.
	When SaveCState was called with two values to save, a subsequent
	GC could cause the RestoreCState to fail because the saved state had been
	promoted to tagless pair.
