 I can't think of a good way to warn users.  Hopefully, this thread will be
a landmark folks can find if they have similar problems, though again I
never would have suspected CMake to blame on this.  Are there other flags
such as this that CMake sets that could affect program behavior like this?
 If so, they should probably be removed with a policy.  Having your build
system add "magic flags" is generally a bad idea.
