Hi Peter,

This change looks correct.  There are two points to consider:
* choice of the option name.  Does GCC have a similar option?  Does
GCC have a name for this extension in the documentation?
* this change needs tests.  You can model tests for this option based
on this example:

http://llvm.org/viewvc/llvm-project/cfe/trunk/test/SemaCXX/warn-static-const-float.cpp?revision=173841&view=markup

The new test file should go into the same directory as the example.
