I don't understand what you want the compiler to do with this.
If it a common idiom to write

    if (foo)
       do-something-with-foo(args);

especially with weak linkage.  See Glibc source for example.
On the other hand it is also quite common to see codes like

  if (ENABLE_CHECKING)
     do-some-debug-mode-stuff  

(where ENABLE_CHECKING is a constant expression either 0 ou 1).
Surely we don't want to ouput noise on those constructs.

I'm going to close this PR.
