[Lazarus] Passing Enum as Parameter

[DSK]

Tired of thunking my head against the monitor trying to figure this out. 
I'm trying to port a tool written in Lazarus to Delphi. The tool uses 
tiOPF is called tiMapper and I'm trying to build the accompanying test 
unit. One of the huge number of compile errors I'm trying to sort out is:
function    FindByGender(const AGender: enum): integer;
[DCC Error] person_bom.pas(92): E2003 Undeclared identifier: 'enum'

Is 'enum' a valid identifier in Lazarus?

Sorry but F1 provides nothing and google comes back with 17 bazillion hits 
and not one means a damn thing to me.

Thanks,
