widl [1/7]: Fix warning about unused structure field in lexer.

[Dan Hipschman]

This series of pathces just enables us to build widl with -W and not get
any complaints from the compiler.  Even if we don't build with -W, at least
it cleans up some code and in one case (the second to last one), fixes a
bug.

This one gets rid of a hundred or so like this:

parser.l:177: warning: missing initializer

ChangeLog:
* Remove an unused structure field (and warnings about not initializing it).
