PROMOTED_MODE_T is defined in src/config.h, please see what happened
there.  On my system, I see this in config.h:

  /* Define to the type that is the result of default argument promotions of
     type mode_t. */
  #define PROMOTED_MODE_T int

On another system I see this:

  /* Define to the type that is the result of default argument promotions of
     type mode_t. */
  #define PROMOTED_MODE_T mode_t
