* procfs.c (procfs_make_note_section): Make the default
	implementation return an error.

2002-02-13  Rodney Brown  <rbrown64@csc.com.au>

	* procfs.c (procfs_make_note_section): Provide a default definition
	(for alpha-dec-osf4.0f). Fix typos.

2002-02-11  Michael Snyder  <msnyder@redhat.com>

	* procfs.c: Include elf-bfd.h (for elfcore_write functions).
	(gcore section): Ifdef for Solaris and Unixware only.
	(procfs_do_thread_registers): Unixware needs one lwpstatus
	per thread (not one prstatus or pstatus).
	(procfs_make_note_section): Iterate only over kernel threads (lwps),
	not over all gdb threads.  For unixware, call elfcore_write_pstatus
	once before iterating over threads.

* memattr.c (create_mem_region): Disallow useless empty region. Regions
are half-open intervals, so allow [A..B) [B..C) as non-overlapping.
