This patch makes the warning for internal procedures whose name is the 
same as the one of an intrinsic clearer. Initially, I though that one 
shouldn't warn for internal procedures, but others disagree. In any 
case, the warning text is better than original one.

Build and regstested on x86-64-linux.
OK for the trunk?
