update_version: Do not check in files which are unchanged.

maintainer-scripts:
	* update_version: Do not check in files which are unchanged.
	* gcc_release: Only update the version in gcc/version.c.
gcc:
	* version.c (version_string): Now const char[].
	* version.h: Update to match.
gcc/ada:
	* Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
	* Makefile.in (TOOLS_LIBS): Add ../../version.o.
	* gnatvsn.ads: Gnat_Version_String is now a function.
	* gnatvsn.adb: New file.  When asked for Gnat_Version_String,
	copy the C version_string into a String and return it.
	* gnatcmd.adb, gnatkr.adb, gnatlbr.adb, gnatlink.adb,
	gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
	Remove pragma Ident (Gnat_Version_String).  If this was the
	sole use of package Gnatvsn, remove the with statement too.
	* gnat1drv.adb: Tweak -gnatv output.
gcc/f:
	* Make-lang.in (g77spec.o): Don't depend on f/version.h.
	(f/parse.o): Depend on version.h not f/version.h.
	(g77version.o, f/version.o): Delete all references.

	* com.c (ffecom_init_0): Fix transposed array indices in bsearch test.
	* g77spec.c: Don't include f/version.h or refer to ffe_version_string.
	* parse.c: Use version_string, not ffe_version_string.
	* version.c, version.h: Delete files.
libf2c:
	* libF77/Version.c: Rename junk to __LIBF77_VERSION__.  Add
	external decls for __LIBI77_VERSION__ and __LIBU77_VERSION__.
	Delete __G77_LIBF77_VERSION__
	(g77__fvers__): Print all three __LIB*77_VERSION__ strings,
	and __VERSION__ if we have it; nothing else.

	* libI77/Version.c: Provide only __LIBI77_VERSION__ (formerly junk).
	* libU77/Version.c: Provide only __LIBU77_VERSION__ (formerly junk).
