2004-10-26 Ed Schonberg <schonberg@gnat.com>
* sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
or protected type with discriminants, do not constrain the
corresponding record type if the subtype declaration has no
discriminant constraints. This can be the case in source code, or in
the subtype declaration created to rename an actual type within an
instantiation.
