;
; Version Incompatible changes in this version
; ------- ------------------------------------
; 0 Initial release of shared runtime
;
; 1 Changed Os2000_Process_Defs to use
; special Ada work area rather than
; user accounting area.
;
; 2 Added 12 long words of spare storage
; in Runtime_Data; this will permit
; some addition of data in the shared
; runtime to be compatible.
;
; 3 1.) Rev 6 compiler
; 2.) Runtime entry point table now 16-bit
; offset from table to entry in words.
; 3.) Deleted some unnecessary shared data items.
; 4.) General cleanup
