+ -- 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.

+ -- file name with no directory information) is the file name for one of the
+ -- predefined library units (i.e. part of the Ada, System, or Interface
+ -- hierarchies). Note that units in the GNAT hierarchy are not considered
+ -- predefined (see Is_Internal_File_Name below). On return, Name_Buffer
+ -- contains the file name. The Renamings_Included parameter indicates
