Fri Nov 20 05:24:16 1992  Jim Blandy  ([e-mail])

	* config.sub: Added machines and operating systems for Emacs
	ports, since Emacs now uses config.sub for its configuration.
	New manufacturers recognized not to be operating systems: High
	Level Hardware (highlevel, defaults to using BSD), Gould
	(gould, defaults to System V), Commodore (cbm, defaults to
	amigados), National Semiconductor (ns, defaults to Genix), and
	Masscomp (masscomp, defaults to RTU).
	Recognize the NS1600 (ns16k) and the Clipper (clipper) as
	processors.
	Recognize these processors with default manufacturers: the
	Cydra (cydra) from Cydrome (cydrome), the XPS100 (xps100) from
	Honeywell (honeywell), and the Orion (orion) and Orion 1/05
	(orion105) from High Level Hardware (highlevel).
	If the ISC operating system is given with a version number,
	don't kill it and set it to 2.2; just have it default to 2.2
	if omitted.
	Make Irix SGI's default operating system, not SYSV.
	Make BSD Encore's default, so it applies for all Encore
	machines, not just the umax and mmax abbreviations.
	All of Encore's machines use BSD, not just the ns32k-based
	ones.  Make it the manufacturer's default.
	Make it possible to specify an operating system for a Gould
	machine.  Make sysv the manufacturer's default, so it applies
	when we specify the manufacturer as well as when we omit it.
	Add Uniplus (uniplus), Iris (iris), Xenix (xenix), and RTU
	(rtu) as recognized operating system names.

Wed Nov 18 17:58:18 1992  Karl Berry  ([e-mail])

	(DBX_DEBUGGING_INFO): #define.

	* cp-decl2.c (grokfield): If the init field is really a list with

	don't treat it like one.

	Tue Nov 10 16:21:20 1992  Brendan Kehoe  ([e-mail])
 
        * cp-init.c (build_new): If arg 1 of an array reference is an
        error_mark, then just pretend that there were 0 elements.

	* cp-typeck.c (build_x_function_call): If the type of FUNCTION is an

	Tue Nov 10 12:38:36 1992  Mike Stump  ([e-mail])

	* cp-decl.c (decls_match): Avoid core dumping when TREE_TYPE is

	Tue Nov 10 11:03:36 1992  Brendan Kehoe  ([e-mail])
 
        * cp-decl.c (pushdecl_top_level): Disable assert for now; it's

	pedwarn about ANSI C.

	* cp-call.c (find_scoped_type): Delete arg TAGS; instead, compute it
	inside from TYPE.  If TAGS is null, don't return immediately, since
	we need to look for TYPE_DECLs.

	in the class declaration.

	* cp-decl2.c (finish_file): Set the DECL_CLASS_CONTEXT on a function
	that's a file-scope set of ctors/dtors for global variables, so
	is_friend will see things the way they should be seen.

	* cp-call.c (find_scoped_type): New function.
	(resolve_scope_to_name): Use it to check for names that might be in
	base classes.

	virtual function.

	from abort when creating the RTL for the newdecl.

	Tue Nov  3 00:15:44 1992  Brendan Kehoe  ([e-mail])

	* cp-decl.c (grokdeclarator): For `inline', `unsigned', and `signed',
	see them as types, not as storage class specs, when looking for more
	than one storage class.

	* cp-lex.c (readescape): New arg ignore_ptr.
	(real_yylex): Pass new arg, handle result that comes back.

	* cp-decl.c (WCHAR_TYPE_SIZE): Deleted; never used.

	(lang_decode_option): Handle -Wchar-subscripts.
	* cp-typeck.c (build_array_ref): If the type of either the array or
	its index is an error_mark_node, then return one.  Add code to see
	if the index is a character (add warning), then do the default
	promotions.  Don't warn if it's a register array. Make a ref
	volatile if the array is volatile.
	* cp-tree.h (warn_char_subscripts): Add decl.

	* cp-typeck.c (common_type): If either type is nonsense (an
	error_mark), use the other type.

	* cp-decl.c (grokdeclarator): Fix problem introduce by me on Oct 22
	17:41:13.  Put back call to build_offset_type that I took out, as it
	is not wrong, as the comment for build_offset_type had led me to
	believe.

	Thu Oct 29 17:30:12 1992  Brendan Kehoe  ([e-mail])
