* Makefile.in configure configure.in: Remove ENABLE_CLIBS, 

ENABLE_OBS, and THREAD_DB_OBS.  These are consolidated into LIBS
	and CONFIG_OBS.
	* configure configure.in:  Clean up test cases around thread support.
start-sanitize-v850
	* configure.tgt (v850-*-*):  Include v850ice.o and v850.lib if
	host is Windows.
end-sanitize-v850
	* c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
	printcmd.c valops.c value.h values.c:  Add bfd_section arg to
	value_at and value_at_lazy.
	* coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
	Add bfd_section arg to prim_record_minimal_symbol_and_info.
	* corefile.c gdbcore.h printcmd.c valops.c:  Use read_memory_section
	instead of read_memory.  It takes a bfd_section arg.
	* coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h:  Remove
	unnecessary cast for assignment of struct dbx_symfile_info.
	Struct objfile now uses a real pointer instead of PTR for this
	element.
	* dbxread.c (dbx_symfile_init): Stash bfd section pointers for
	text, data and bss into dbx_symfile_info.
	* exec.c (xfer_memory):  Handle transfers for user-specified
	sections.
	* findvar.c (read_var_value locate_var_value):  Copy bfd section
	from the symbol to the value.
	* gdb-stabs.h:  Add section pointers for text, data and bss
	sections.
	* maint.c (translate address command):  Add test code for overlay
	address translation.
	* printcmd.c (do_examine do_one_display):  Now takes a bfd section
	arg.
	* (print_formatted x_command):  Record current section along with
	current address for repeated commands.
	* sparc-nat.c (fetch_inferior_registers):  Change
	target_xfer_memory to target_{read write}_memory to allow changes
	to target_xfer_memory interface for section info.
	* symmisc.c (dump_msymbols print_symbol):  Print section
	assocaited with symbol.
	* symtab.c (fixup_symbol_section):  New routine to
	add section info to symbols returned by lookup_symbol.
	* symtab.h (struct general_symbol_info):  Add bfd section to
	symbols.
	* target.c target.h (target_xfer_memory):  Add bfd section to
	args.
	* (target_read_memory_section):  New routine to read data from a
	specific section.
	* (target_memory_bfd_section):  New global variable to pass bfd
	section in to targets.
	* valarith.c (value_add value_addr value_array):  Preserve bfd
	section when computing new value.
	* value.h (struct value):  Add bfd section to values.
	* values.c (allocate_value value_copy):  Initialize/preserve bfd
	section.
	* (unpack_double):  Clean up _MSC_VER conditionals to remove
	duplicate code.
start-sanitize-v850
	* v850ice.c:  New module to support communication with NEC's
	PC-based ICE.
	* config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
	ep names with rxx names.  sp and fp are renamed via a different
	mechanism.
