[Bug c++/39487] New: Useless -Wshadow warnings for function pointer parameters

[derefer at gmail dot com]

Consider the following function declaration:

int f(int a, int (*b)(int a));

When compiled with g++ trunk using -Wshadow, some new, probably useless,
warnings appear:

shadow.h:2: warning: declaration of 'int a' shadows a parameter
shadow.h:2: warning: shadowed declaration is here

It seems to be a C++ related issue, since gcc -Wshadow compiles this
declaration with no warnings.  As I see, the new warnings are present from
revision 140120.
