That not absolutely correct.  In translation phase 4 the source
presentation can become relevant again due to the # macro operator.

Since this is your design, you can do what you like with something like

  #define s(t) #t
  s(AND)

but converting AND to && is out of step with existing practice.  Where C
currently has alternate spellings for tokens, these much be recovered
when a token is "stringized".
