I'm not sure that it can be done, or at least done in a way that's 
worth it.

Warnings are completely non-portable, since:

1.	They have no official standing in the standard, just errors do
2.	They are made up by each compiler vendor
3.	They are 100% legal code, the vendor just doesn't like it

These combine into something that cannot be generally tested.  We would 
have to examine every compiler and make huge conditional test cases.  
And what would happen if someone hates warnings and turns them all off? 
  It's not practical.
