    libstdc++: Fix bootstrap on AIX due to fileno macro
    
    On AIX fileno is a function-like macro, so enclose the name in
    parentheses to ensure we use the real function.
    
    libstdc++-v3/ChangeLog:
    
            * src/c++23/print.cc (__open_terminal(FILE*)): Avoid fileno
            macro.
