I don't understand how the line of code you mention helps demonstrate your logic. Two parameters are declared, one called a and one called b. In the standard, the end of paragraph 8.3.5.7 says If a parameter name is present in a function declaration that is not a definition, it cannot be used outside of the parameter-declaration-clause since it goes out of scope at the end of the function declarator So it implies that a new scope is entered at the ( and exited at the ). But we already know that a name can't be reused at the same scope [ except for function overloading, but that's different]. QED. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13717
