Well, I now know what I need to know.  I thank everyone who has sent
me email.  You can stop sending now.  I particularly thank:
Larry Jones, Florian Krohm, dilse2@info.win.tue.nl,
Mark Pledger, Rick Kimball, Thomas J Roberts, and Peter Mielke.

The solution was quite simple actually, I'm embarassed that I didn't
think of it myself; but, that's why I originally asked.

The solution I'll use consists of modifying the lex piece to just parse
"identifiers".  Then, when it finds an identifier, it will look it up
in a "reserved word" table.  If found, it will return the associated token.
If not found, then it returns "identifier".  The lookup will take place
via a C routine, not building it into the lex parse tables like I was doing.

I knew there had to be a better and easier way, and this, I believe, is it.
