    stdio.h: Don't define unlocked macros using static inline on C++
    
    In C++, the usage of static inline functions for getchar_unlocked and
    putchar_unlocked may result in error messages like
    
      error: ‘_putchar_unlocked’ was not declared in this scope
    
    Fix this by not using the _getchar_unlocked and _putchar_unlocked
    macros in C++.
