* binde.adb: Remove with clause for System.OS_Lib.
(Force_Elab_Order): Refactor the majority of the code in Butil.
Use the new forced units iterator to obtain unit names.
* bindo-builders.adb: Add with and use clauses for Binderr,
Butil, Opt, Output, Types, GNAT, and GNAT.Dynamic_HTables. Add
a hash table which maps units to line number in the forced
elaboration order file.
(Add_Unit): New routine.
(Build_Library_Graph): Create forced edges between pairs of
units listed in the forced elaboration order file.
(Create_Forced_Edge, Create_Forced_Edges, Destroy_Line_Number,
Duplicate_Unit_Error, Hash_Unit, Internal_Unit_Info,
Is_Duplicate_Unit, Missing_Unit_Info): New routines.
* bindo-graphs.adb (Is_Internal_Unit, Is_Predefined_Unit):
Refactor some of the behavior to Bindo-Units.
* bindo-graphs.ads: Enable the enumeration literal for forced
edges.
* bindo-units.adb, bindo-units.ads (Is_Internal_Unit,
Is_Predefined_Unit): New routines.
* butil.adb: Add with and use clauses for Opt, GNAT, and
System.OS_Lib. Add with clause for Unchecked_Deallocation.
(Has_Next, Iterate_Forced_Units, Next, Parse_Next_Unit_Name,
Read_Forced_Elab_Order_File): New routines.
* butil.ads: Add with and use clauses for Types. Add new
iterator over the units listed in the forced elaboration order
file.
(Has_Next, Iterate_Forced_Units, Next): New routine.
* namet.adb, namet.ads (Present): New routine.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
