Actually it would.  This:

    struct tree { int n; };
    tree tree;

is legal in C++ (or at least "g++ -std=c++11 -pedantic" doesn't complain
about it).  But after the second declaration, the type name "tree" is
hidden by the object name.

Similar C code using typedef is rejected.  Perhaps the scoping rules are
subtly different.
