35 -- Given a unit name stored in Name_Buffer with length in Name_Len,
36 -- returns True if this is the name of a predefined unit or a child of
37 -- a predefined unit (including the obsolescent renamings). This is used

43 -- an internal. Similar in usage to Is_Predefined_Unit.

46 -- we want to avoid bringing Uname into the binder since it generates
47 -- to many unnecessary dependencies, and makes the binder too large.

58 -- Name_Len is set to the number of characters which were output.
