[Ada] Spurious error on universal access equality operator
2019-12-12 Ed Schonberg <schonberg@adacore.com>
gcc/ada/
* sem_type.adb (Find_Unique_Type): A call to the universal
access equality operator requires one operand to be a universal
access, and the other to be an access type. There is no
requirement, as previously implied by this routine, that
pool-specific access types were illegal in this context.
