Hi, When I compile a header with g++ trunk on x86_64 using -Wshadow containing function declarations like this: int g(int a, int (*b)(int a)); /* Originally, I found it in openssl's bn.h BN_BLINDING_create_param() and I got a bunch of warnings from all .cc files including this header. */ I get: shadow.h:2: warning: declaration of 'int a' shadows a parameter shadow.h:2: warning: shadowed declaration is here I don't see the reason for this warning, because the parameters of the second parameter `b' AFAIK have nothing to do with parameters of the original function `g'. (With gcc -Wshadow it compiles with no warnings.) It seems to me, that the warning is present from g++ 4.4 revision 140120, which was a fix for PR37302. Is it the expected behavior? I haven't checked the standard yet... Thanks in advance. Regards, Ferenc
