Update.

1998-08-09  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/Makefile [subdir=elf]: Add new files split out of
	dl-machine.h.
	* sysdeps/powerpc/dl-machine.c: New file.
	* sysdeps/powerpc/dl-machine.h: Move much stuff into separate
	files.  Revise ELF_PREFERRED_ADDRESS to take account of
	the new mapping information (fixes bug involving huge bloated
	web browser).  Set ELF_MACHINE_PLTREL_OVERLAP.
	* sysdeps/powerpc/dl-start.S: New file.

	* elf/dl-load.c (_dl_map_object_from_fd): Initialise l_map_start,
	l_map_end.
	* elf/do-rel.h: Call elf_machine_rel only once (to save space).
	* elf/dynamic-link.h: Allow PLT relocs to be in the middle of the
	others.  Call elf_dynamic_do_##reloc only once (to save even more
	space).
	* elf/link.h: Add new members l_map_start and l_map_end to keep
	track of the memory map.
	* elf/rtld.c (_dl_start): Initialise l_map_start for ld.so and
	the executable.

	* debug/Makefile (catchsegv): We need not rewrite SOVER anymore.
	Reported by Andreas Jaeger.

	* posix/glob.h: Use __size_t instead of size_t in definitions and
	make sure this is defined.

	* manual/locale.texi: Almost complete rewrite.  Document more functions

 /* Argp example #4 -- a program with somewhat more complicated options */
 
+/* This program uses the same features as example 3, but has more
+   options, and somewhat more structure in the -help output.  It
+   also shows how you can `steal' the remainder of the input
+   arguments past a certain point, for programs that accept a
+   list of items.  It also shows the special argp KEY value
+   ARGP_KEY_NO_ARGS, which is only given if no non-option
+   arguments were supplied to the program.
+
+   For structuring the help output, two features are used,
+   *headers* which are entries in the options vector with the
+   first four fields being zero, and a two part documentation
+   string (in the variable DOC), which allows documentation both
+   before and after the options; the two parts of DOC are
+   separated by a vertical-tab character ('\v', or '\013').  By
+   convention, the documentation before the options is just a
+   short string saying what the program does, and that afterwards
+   is longer, describing the behavior in more detail.  All
+   documentation strings are automatically filled for output,
+   although newlines may be included to force a line break at a
+   particular point.  All documenation strings are also passed to
+   the `gettext' function, for possible translation into the
+   current locale.  */
