The amplification of rule 20.8 states:
Quote: This rule does not apply to controlling expressions in preprocessing directives which are not evaluated. Controlling expressions are not evaluated if they are within code that is being excluded and cannot have an effect on whether code is excluded or not.
Therefore this rule does not apply to the "#elif 20". However the "#if 10" is a violation of rule 20.8
