From: Javier Miranda <mira...@adacore.com>
The compiler rejects performing a dispatching call using the
prefix notation when the prefix of the call is a mutably
tagged class-wide type object.
gcc/ada/ChangeLog:
* sem_ch4.adb (Try_Object_Operation): Handle mutably tagged
class-wide type prefix.
Tested on x86_64-pc-linux-gnu, committed on master.
