c4413e2c9b * c-exp.y (exp:STRING): Convert C strings into array-of-char
constants with an explicit null byte terminator.  OP_STRING is
	now used for real string types.

	are printed as strings to be consistent with the way strings

94603999f9 A bunch of changes mostly to improve debugging of C++ programs.
Specifically, the calling of inferiors methods is improved.

	* value.h:  New macros METHOD_PTR_IS_VIRTUAL,
	METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
	hide the implementation details of pointer-to-method objects.
	How to tell if the pointer points to a virtual method is
	still very dependent on the particular compiler, but this
	should make it easier to find the places to change.
	* eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
	(val_print [case TYPE_CODE_PTR]):  Use the new METHOD_PTR_*
	macros, instead of a hard-wired-in code that incorrectly
	assumed a no-longerused representation of pointer-to-method
	values.  And otherwise fix the relevant bit-rotted code.

	* valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
	If there are both fields and methods, put a space between.

	* stabsread.c (read_struct_type):  Fix bug in handling of
	GNU C++ anonymous type (indicated by CPLUS_MARKER followed
	by '_').  (It used to prematurely exit the loop reading in
	the fields, so it would think it should start reading
	methods while still in the fields.  This could crash gdb
	given a gcc that can emit nested type information.)

	* valops.c (search_struct_method):  Pass 'this' value by
	reference instead of by value.  This provides a more
	consistent interface through a recursive search where the
	"bottom" functions may need to adjust offsets (due to multiple
	inheritance).
	* valops.c, value.h, values.c:  Pass extra parameters to
	value_fn_field and value_virtual_fn_field so we can
	correctly adjust offset for multiple inheritance.
	* eval.c (evaluate_subexp [case OP_FUNCALL]):  Simplify
	virtual function calls by using value_virtual_fn_field().
	* values.c: New function baseclass_offset, derived from
	baseclass_addr (which perhaps can be made obsolete?).
	It returns an offset rather than an address.  This is a
	cleaner interface since it doesn't mess around allocating
	new values.

ae0ea72ee2 Changes to support GDB running on DOS using GO32 and H8 support
* defs.h: if xm.h doesn't define FOPEN_RB, include "fopen-same.h",
	allowing hosts with different text and binary file formats to
	work.
	* coffread.c (read_coff_symtab): changed calling convention and
	operation - now it opens its own file with FOPEN_RB rather than
	duping and fdopening the provided handle.
	* dbxread.c, cplus-dem.c: #include mangling.
	* exec.c: If O_BINARY isn't defined, set it to 0, call openp for
	binary files oring in the right bit.
	* utils.c, terminal.h, inflow.c: hackery because dos doesn't have terminals.
	* remote-hms.c: cleanup to use the new remote serial stuff
	* serial.h, ser-termios.c, ser-go32.c: newfiles to provide host
	independent remote terminal I/O.
	* remote.c: if DONT_USE_REMOTE is defined, then don't use it.
	* source.c (openp): fix off by one problem removing / - can now
	open a source file in the root directory with DOS.
	* values.c (value_as_pointer): remove bogus address bits from
	long. (unpack_long): unpack into unsigned long/short if pointer.

Allows selection of C++ demangler to be a configuration option
	until multiple demanglers are supported.
	* demangle.h:  New include file for extended demangler support.
	* breakpoint.c, gdbtypes.c, printcmd.c, stack.c, symtab.c,
	utils.c, valprint.c:  Include "demangle.h" and change all calls
	to cplus_demangle() or fputs_demangled() to use individual
	demangling options.
	* valprint.c (type_print_1):  Change options to cplus_demangle
	to print demangled function args.  Still broken, but now less so.
	* cplus-dem.c:  Include demangle.h, reorganize and update some
	comments to reflect reality.
	* cplus-dem.c (cplus_demangle, cplus_mangle_opname):  Change
	second arg from fixed integer to bit based multiple options.
	* cplus-dem.c (optable):  Reformat and replace ansi members with
	bit based options.
	* cplus-dem.c (do_type):  Fix bug with parsing missing return type.

	* symtab.h:  Fix couple of misspellings in comments.
	* value.h (struct value):  Clarify use of bitpos.
	* value.h (unpack_field_as_long):  Change prototype, returns

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

(Idea from pierre@la.tce.com (Pierre Willard).)
