title: How To Ignore Warnings With GCJ
body: <p>I have some classes that implement interfaces, some of which have methods whose parameters are by definition unused in the particular class implementation. e.g. A "Shape" interface may define a "contains(point)" method, but my particular class defines a line, which cannot contain anything since it's 1-dimensional, so it always returns false and never uses point.</p>
  
  <p>However, when I compile with GCJ, I'm assaulted with hundreds of "warning: parameter x is unused" messages.</p>
  
  <p>I tried using the -Wno-all flag to disable warnings, as well as the others documented in gcj's manpage, but these have no effect. How do I instruct GCJ to not bother me with these trivial warnings?</p>
