From: Bob Duff <d...@adacore.com>
The compiler gives a wrong error for a call of the form X.Y(...)
when Y is inherited indirectly via an interface.
gcc/ada/
* sem_ch4.adb (Is_Private_Overriding): Return True in the case
where a primitive operation is publicly inherited but privately
overridden.
Tested on x86_64-pc-linux-gnu, committed on master.
