It is an issue with consolidation patch, the LO_HI_LONG should be guarded
as:
 
 /* Provide a macro to pass the off{64}_t argument on p{readv,writev}{64}.  */
-#if __WORDSIZE == 64 || defined __ASSUME_WORDSIZE64_ILP32
+#ifdef __OFF_T_MATCHES_OFF64_T
 # define LO_HI_LONG(val) (val)
 #else
 # define LO_HI_LONG(val) \

I will send with this change.
