That means that if a body of certain OpenMP construct uses t%re or t%im, it is
treated as if it references the whole t.

Sure, in expressions it is fine.  Parts of variables are generally allowed in
e.g. map clause.  For the privatization clauses with a few exceptions one needs
to specify a variable name in the list alone and that privatizes the whole
variable.  Exceptions are e.g. exactly for reduction clauses in [131:7] - array
sections are allowed in reduction clauses (that is the unless otherwise
specified), or e.g. in C++ in methods one can privatize members of the current
class separately from the whole class object.
