! { dg-do compile }
! { dg-options "-Wunused-variable -Wunused-parameter" }
! This tests the fix for PR18111 in which some artificial declarations
! were being listed as unused parameters:
! (i) Array dummies, where a copy is made;
! (ii) The dummies of "entry thunks" (ie. the articial procedures that
! represent ENTRYs and call the "entry_master" function; and
! (iii) The __entry parameter of the entry_master function, which
! indentifies the calling entry thunk.
! All of these have DECL_ARTIFICIAL (tree) set.
