Different behavior of g++ and gcc (both egcs) compilers

[Alex Vinokur]

Hi,

Here is a simple program.
Why is the g++ and gcc (both egcs) compilers' behavior different?

        Thanks in advance,
        Alex

void foo (char a [n])

}

int main()
{
        return 0;
}


//------------------- C++ code : END ----------------------

%g++ main.c
