If there are multiple tasks of that type, or if there are multiple tasks with
"pragma Import"s using the same "External_Name" value, yes.

Yes again. If the body of a subprogram is physically *in* the task's body,
then every task gets its own copy of that subprogram (along with all the
other objects it declares). However, the body for the "pragma Import" is
really in an object file which was declared (in C) at the top scope level. In
this sense, its much like doing a "renames" clause on a library unit.
