29 -- This package contains data and functions used to determine if a given
30 -- unit is an internal unit intended only for use by the implementation
31 -- and which should not be directly WITH'ed by user code.
33 with Types; use Types;
37 function Implementation_Unit (U : Unit_Number_Type) return Boolean;
38 -- Given the unit number of a unit, this function determines if it is a
39 -- unit that is intended to be used only internally by the implementation.
40 -- This is used for posting warnings for improper WITH's of such units
41 -- (such WITH's are allowed without warnings only in GNAT_Mode set by
42 -- the use of -gnatg). True is returned if a warning should be posted.
