Indeed! I removed this call, rebuilt libgcj and reran the testsuite (including
Jacks) and there were no regressions (only the two "err6" failures that are
anyway seen on mainline today).

FWIW, here's the "expand_*" usage in the GCJ front end:
------------------------------ 8< ------------------------------
expr.c:      expand_eh_region_start ();
expr.c:      expand_start_all_catch ();
expr.c:   expand_start_catch (prepare_eh_table_type (type));
expr.c:   expand_end_catch ();
expr.c:      expand_end_all_catch ();
expr.c: expand_decl (array_decl);
expr.c:       expand_decl (pushdecl (local));
expr.c: tmp = expand_assignment (array_decl,
expr.c: expand_assignment (build (COMPONENT_REF, TREE_TYPE (data_fld),
class.c:      expand_function_start (init_decl, 0);
resource.c:  expand_function_start (init_decl, 0);
class.c:      expand_function_end ();
resource.c:  expand_function_end ();
expr.c:  expand_goto (target_label);
expr.c:  expand_goto (target_label);
expr.c:      expand_expr_stmt (TREE_OPERAND (exp, 0));
expr.c:   expand_expr_stmt (TREE_OPERAND (current, 0));
expr.c:  expand_expr_stmt (build (MODIFY_EXPR, boolean_type_node,
expr.c:   expand_end_bindings (getdecls (), 1, 0);
expr.c: expand_decl (array_decl);
expr.c:       expand_decl (pushdecl (local));
------------------------------ 8< ------------------------------

Should these be removed/replaced as well?
