| -- This package contains data and functions used to determine if a given |
| -- unit is an internal unit intended only for use by the implementation |
| -- and which should not be directly WITH'ed by user code. It also checks |
| -- for Ada 05 units that should only be WITH'ed in Ada 05 mode. |

| -- Unit from predefined library intended to be used only by the |
| -- compiler generated code, or from the implementation of the run time. |
| -- Use of such a unit generates a warning unless the client is compiled |
| -- with the -gnatg switch. If we are being super strict, this should be |
| -- an error for the case of Ada units, but that seems over strenuous. |

| Not_Predefined_Unit, |
| -- This is not a predefined unit, so no checks are needed |
| |
| Ada_95_Unit, |
| -- This unit is defined in the Ada 95 RM, and can be freely with'ed |
| -- in both Ada 95 mode and Ada 05 mode. Note that in Ada 83 mode, no |
| -- child units are allowed, so you can't even name such a unit. |
| |
| Ada_05_Unit); |
| -- This unit is defined in the Ada 05 RM. Withing this unit from a |
| -- Ada 95 mode program will generate a warning (again, strictly speaking |
| -- this should be an error, but that seems over-strenuous). |

| -- Given the unit number of a unit, this function determines the type |
| -- of the unit, as defined above. |
