Avoid more warnings in flex-generated code.
This avoids two "function defined but not used" warnings. For the yyinput
function we define YY_NO_INPUT which tells flex to simply not generate this
function.
For unput, we add a call to this function, but inside a while(0) so
that it will quiet the warning without actually changing any
functionality.
