Yes, that works, though UNUSED is a confusing name to attach to a 
variable, as the variable is actually used. A better name is UNINIT, 
indicating that the variable is uninitialized. Similarly, NONVOLATILE 
could indicate that a variable is not volatile, in cases where GCC would 
otherwise complain. The attached patch would suffice to omit all uses of 
the IF_LINT macro in the Emacs source, if that's a style you prefer.
