title: gcc how to suppress incompatible pointer type warning?
body: <p>In our project warnings are treated as Error. This rule is applied from top level makefile.</p>
  
  <p>I want to suppress warnings for the third party code.</p>
  
  <p>I am getting "incompatible pointer type" warning when passing arguments to a function call.</p>
  
  <p>I tried "-Wno-incompatible-pointer-types". But, its not supported by the compiler.</p>
  
  <p>I'm using gcc.c4.2.1-p4.ppc-linux.</p>
  
  <p>Can someone tell me how to suppress this "incompatible pointer type" warning?</p>
