Test case.

Overview:
    Both MSVC (http://msdn.microsoft.com/en-us/library/2bcktt82) and GCC do not
allow for a member variable/function of a class to have the same name as the
class. Clang (both 2.7 and compiled from SVN r101755) will compile the attached
test case with no warning or error and the program runs as expected.

I am not a standards guru, so I am not sure if this is in the standard or not.

Steps to Reproduce:
   1) Run clang on test.cpp.

Actual Results:
   No warnings/errors, and a fully working executable.

Expected Results:
   A warning or error (like gcc's "test.cpp:9: error: field 'int C::C' with
same name as class")
