purpose: Tokenizer macros - one word expands to several FCodes
copyright: Copyright 1996-2004 Sun Microsystems, Inc.  All Rights Reserved
copyright: Use is subject to license terms.

\ Cross-compiler equivalents for tokenizer system
\ "All accounted for" means that, for this section, all non-primitives
\ are named (and either defined, or at least mentioned.)


\  In order to prevent multi-token macros from being accepted as
\      targets of ['] or ' (so-called "tick-targets"), we check
\      for seeming-tokens that are actually colon-definitions or
\      the like.  However, some single-token macros are valid
\     "tick-targets" anyway.
\  The operator  valid-tick-target  will qualify the last definition
\      as a valid tick-target. 


\ --- IEEE 1275 and ANS Forth name changes ------------------------------

\  As it happens, all the  v2-compat:  definitions are valid "tick-targets"
\      but this need not be necessarily so.  Therefore, I am not going to
\      include the  v2-compat:  defining-word in the list of word-types
\      that are valid "tick-targets", nor am I going to mark these words
\      individually with the  valid-tick-target  operator.
\  Instead, I will make  v2-compat:  do the checking and mark the new words
\      appropriately.  I will merely append a  v-t-t  comment...
