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

Unattributed changes are by David N. Williams.  Last revision
dates in source files may reflect cosmetic changes not recorded
here.

Version 1.0.5
22Aug21 * Removed GFORTH conditional in plainstruct.fs in favor of
	  individual [UNDEFINED] conditionals.
	* Revised plainstruct-test.fs to use ttester-xf.
24Aug21 * Removed obsolete S" FLOATING-EXT" ENVIRONMENT? in favor of
	  test for F@.
	* Revised /STRUCT to remove trailing structure alignment.  This
	  was a significant conceptual error.
	* Made SF, DF, and QF words and MAXALIGNED conditional on
	  existence of SFALIGNED, DFALIGNED, and QFALIGNED.
	* Adjusted tests for above changes.
	* Made MAXALIGNMENT in tests conditional on existence of
	  DFALIGNED, and QFALIGNED.
25Aug21 * Documented absence of trailing alignment.

Version 1.0.4
 7Jul10 * Removed USE-STATE-SMART-FIELDS and state-smart version
	  of +FIELD.
	* Added ]&, for explicit early binding without state
	  smartness.
	* Added:  MAKE-STRUCT:   MAKE-IMM-STRUCT: 
		  MAKE-FSTRUCT:  MAKE-IMM-FSTRUCT:
		  MAXALIGN  MAXALIGNED  FSTRUCTFIELD:
	* Added tests for 2's complement and 2^n alignment,
	  assumed by MAXALIGNED.
	* Added GFORTH conditional.
 9Jul10 * Simplified MAXALIGNED, idea borrowed from Andrew
	  Haley.
 4Aug10 * Updated ANSI color support in plainstruct-test.fs.

Version 1.0.3
20Jun10 * Added STRUCTFIELD:, with tests.
	* Revised stack comments to use a-offset, fa-offset,
	  sfa-offset, dfa-offset, as appropriate.
	* Added compiled access tests, missing for some fields.
21Jun10 * Made the fp structure instance in plainstruct-test.fs
	  explicitly DFALIGNED, because CREATE is not required
	  to do that.

Version 1.0.2
16Jun10 * Reverted to the reference implementation of +FIELD as
	  default, with the optimizing version selectable by
	  external definition of the constant
	  USE-STATE-SMART-FIELDS with value TRUE.

Version 1.0.1
11Jun10 * Revised +FIELD to optimize compilation of field offset
	  words, based on the approach in Hugh Aguilar's novice
	  forth package.
12Jun10 * Added tests:  STRUCT  /STRUCT:  +FIELD
13Jun10 * Renamed plainstruct-200x.fs as plainstruct.fs.
	* Fixed alignment omission in 2FIELD: and SFIELD:.
	* Separated tests into plainstruct-test.fs.
	* Added tests:  FIELD:  CFIELD:  FIELD:  2FIELD:  SFIELD:
			FFIELD:  SFFIELD:  DFFIELD:
	* Revised conditional fp compilation.
	* Revised comments.

Version 1.0.0
 1Aug08 * Renamed as plainstruct-200x.fs.
	* Modified names to conform to Forth 200x structure
	  proposal.
	* Added from 200x proposal:  FFIELD:  SFFIELD:  DFFIELD:
25Apr09 * Fixed stack picture for 2FIELD: and SFIELD:, and
	  removed extra +.

24Aug02 * Original version start.
26Aug02 * Mitch Bradley attribution.
