---------------------------
-- File Name Conventions --
---------------------------
-- GNAT requires that there be a one to one correspondence between source
-- file names (as used in the Osint package interface) and unit names as
-- defined by the Uname package. This correspondence is defined by the
-- two subprograms defined here in the Fname package.
-- For full rules of file naming, see GNAT User's Guide. Note that the
-- naming rules are affected by the presence of Source_File_Name pragmas
-- that have been previously processed.
-- Note that the file name does *not* include the directory name. The
-- management of directories is provided by Osint, and full file names
-- are used only for error message purposes within GNAT itself.

-- This function determines if the given file name (which must be a simple
-- file name with no directory information) is the file name for one of
-- the predefined library units. On return, Name_Buffer contains the
-- file name. The Renamings_Included parameter indicates whether annex
-- J renamings such as Text_IO are to be considered as predefined. If
-- Renamings_Included is True, then Text_IO will return True, otherwise
-- only children of Ada, Interfaces and System return True.
