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 #2 -- a pretty minimal program using argp */
 
+/* This program doesn't use any options or arguments, but uses
+   argp to be compliant with the GNU standard command line
+   format.
+
+   In addition to making sure no arguments are given, and
+   implementing a --help option, this example will have a
+   --version option, and will put the given documentation string
+   and bug address in the --help output, as per GNU standards.
+
+   The variable ARGP contains the argument parser specification;
+   adding fields to this structure is the way most parameters are
+   passed to argp_parse (the first three fields are usually used,
+   but not in this small program).  There are also two global
+   variables that argp knows about defined here,
+   ARGP_PROGRAM_VERSION and ARGP_PROGRAM_BUG_ADDRESS (they are
+   global variables becuase they will almost always be constant
+   for a given program, even if it uses different argument
+   parsers for various tasks).  */
