90 - Retysp which is used to query the most underlying type
91 visible in SPARK. We do not introduce aliasing checks for
92 types which are not visibly deep.
93 - Component_Is_Visible_In_SPARK is used to avoid doing pointer
94 aliasing checks on components which are not visible in SPARK.
95 - Emit_Messages returns True in the second phase of SPARK
96 analysis. Error messages for failed aliasing checks are only
97 output in this case.
98 Additionally, errors on constructs not supported in SPARK are
99 removed as duplicates of marking errors. Components are stored

117 declaration in an extended return statement.
