Where KEYWORD is the macro that gets replaced in the lexical phase,
and REPLACEMENT is a string that is inserted in its place.  Empty string
implies that the lexical analyzer will discard KEYWORD when it is encountered.

Alternately, it can be of the form:
  ( \"KEYWORD\" ( LEXSYM1 \"str\" 1 1 ) ... ( LEXSYMN \"str\" 1 1 ) )

lexical analyzer, such as `symbol' or `string'.  The string in the
second position is the text that makes up the replacement.  This is
the way to have multiple lexical symbols in a replacement.  Using the
first way to specify text like \"foo::bar\" would not work, because :
is a separate lexical symbol.

A quick way to see what you would need to insert is to place a
definition such as:

#define MYSYM foo::bar
