Craig Burley 95a1b67649 Restore circa-0.5.22 capabilities of `g77' driver:
Thu May 28 21:32:18 1998  Craig Burley  <burley@gnu.org>
	Restore circa-0.5.22 capabilities of `g77' driver:
	* Make-lang.in (g77spec.o): Depend on f/version.h.
	(g77version.o): New rule to compile g77 version info.
	(g77$(exeext)): Depend on and link in g77version.o.
	* g77spec.c: Rewrite to be more like 0.5.22 version
	of g77.c, making filtering of command line smarter
	so mixed Fortran and C (etc.) can be compiled, verbose
	version info can be obtained, etc.
	* lang-specs.h (f77-version): New "language" to support
	"g77 -v" command under new gcc 2.8 regime.
	* lex.c (ffelex_file_fixed): If -fnull-version, just
	substitute a "source file" that prints out version info.
	* top.c, top.h: Support -fnull-version.
	* lang-specs.h: Use "%O" instead of OO macro to specify
	object extension.  Remove old stringizing cruft.
	* Make-lang.in (g77.c, g77spec.o, g77.o, g77$(exeext),
	g77-cross$(exeext), f771,
	$(srcdir)/f/g77.info, $(srcdir)/f/g77.dvi,
	$(srcdir)/f/intdoc.texi,
	f77.install-common, f77.install-info, f77.install-man,
	f77.uninstall, $(G77STAGESTUFF), f77.stage1, f77.stage2,
	f77.stage3, f77.stage4, f77.distdir): Don't do anything
	unless user specified "f77" or "F77" in $LANGUAGES either
	during configuration or explicitly.  For convenience of
	various tests and to work around lack of the assignment
	"LANGUAGES=$(BOOT_LANGUAGES)" in the "make stage1" command
	of "make bootstrap" in gcc, use a touch file named "lang-f77"
	to communicate whether this is the case.
	* Make-lang.in (F77_FLAGS_TO_PASS): Delete this macro,
	replace with minimal expansion of its former self in
	each of the two instances where it was used.
	* Makefile.in (HOST_CC): Delete this definition.
	* com.c (index, rindex): Delete these declarations.
	* proj.h: (isascii): Delete this.
	* Make-lang.in (f77.install-common): Warn if `f77-install-ok'
	flag-file exists, since it no longer triggers any activity.
	Rename libf2c.a and f2c.h to libg2c.a and g2c.h,
	normalize and simplify g77/libg2c build process:
	* Make-lang.in: Remove all support for overwriting
	/usr/bin/f77 etc., or whatever the actual names are
	via $(prefix) and $(local_prefix).  (g++ overwrites
	/usr/bin/c++, but then it's often the only C++ compiler
	on the system; f77 often exists on systems that are
	installing g77.)
	(f77.realclean): Remove obsolete target.
	(g77.c, g77$(exeext)): Minor changes to look more like g++'s
	stuff.
	(f771): Now built with srcdir=gcc/f, not srcdir=gcc, to be
	more like g++ and such.
	(f/Makefile): Removed, as g++ doesn't need this rule.
	(f77.install-common): No longer install f77, etc.
	(f77.install-man): No longer install f77.1.
	(f77.uninstall): No longer uninstall f77, f77.1, etc.
	(f77.stage1, f77.stage2, f77.stage3, f77.stage4): Do work
	only if "f77" appears in $(LANGUAGES).
	(Note: gcc's Makefile.in's bootstrap target should set
	LANGUAGES=$(BOOT_LANGUAGES) when making the stage1 target.)
	* Makefile.in: Update vis-a-vis gcc/cp/Makefile.in.
	(none): Remove.
	(g77-only): Relocate.
	(all.indirect, f771, *.o): Now assumes current directory
	is this dir (gcc/f), not the parent directory.
	(TAGS): Remove "echo 'parse.y,0'  >> TAGS ;" line.
	* config-lang.in: Delete commented-out code.
	Fix stagestuff definition.  Add more stuff to
	diff_excludes definition.  Don't create any directories.
	Set outputs to f/Makefile, to get variable substition
	to happen (what does that really do, anyway?!).
	* g77spec.c: Rename libf2c to libg2c.
	* com.h: Remove all of the gcc back-end decls,
	since egcs should have all of them correct.
	* com.c: Include "proj.h" before anything else,
	as that's how things are supposed to work.
	* ste.c: Ditto.
	* bad.c: Include "flags.j" here, since some diagnostics
	check flag_pedantic_errors.
	* Makefile.in (f/*.o): Rebuild dependencies via
	deps-kinda.
	* output.j: New source file.
	* Make-lang.in (F77_SRCS): Update accordingly.
	* Makefile.in (OUTPUT_H): Ditto.
	(deps-kinda): Ditto.
	* com.c: Include "output.j" here.
	* lex.c: Ditto.

README

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
