    // The initial mode for _fmode is initialized during pre_c_initializer() in vcstartup, so that it can be overridden with a linkopt.
    // The default value is provided by _get_startup_file_mode(), but this value is not used to initialize both _fmode states.
    // (ex: if exe is Prog-Mode, OS-Mode _fmode is uninitialized, if exe is OS-Mode, Prog-Mode _fmode is uninitialized)
 
    // To fix this, we adjust zero-value _fmode to _O_TEXT, since that is the default.
    // Only the exe can use the linkopt, so the state that is not being initialized could not have requested _O_BINARY.
