* dispextern.h (Qframe_set_background_mode): Remove decl.

 src/xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'

on undefined behavior with wrong number of arguments.
(dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
Don't assume ptrdiff_t and EMACS_INT are the same width as int.
In this code, it's OK to assume C99 behavior for ptrdiff_t formats
since we're not interested in debugging glyphs with old libraries.

	The next log entry shows the actual changes by Paul Eggert.

 Fix a problem with aliasing and vector headers.
 GCC 4.6.0 optimizes based on type-based alias analysis.  For
 example, if b is of type struct buffer * and v of type struct
 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
 != &v->size, and therefore "v->size = 1; b->size = 2; return
 v->size;" must therefore return 1.  This assumption is incorrect
 for Emacs, since it type-puns struct Lisp_Vector * with many other
 types.  To fix this problem, this patch adds a new type struct
 vector_header that documents the constraints on layout of vectors
 and pseudovectors, and helps optimizing compilers not get fooled
 by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
 src/lisp.h (XVECTOR_SIZE): New convenience macro.  All previous uses of
 XVECTOR (foo)->size replaced to use this macro, to avoid the hassle
 of writing XVECTOR (foo)->header.size.
 src/lisp.h: Say "vectorlike header" rather than "vector header.
 (struct vectorlike_header): Rename from struct vector_header.
 (XVECTORLIKE_HEADER_SIZE): Renamed from XVECTOR_HEADER_SIZE.
 All uses changed.
 (XVECTOR_HEADER_SIZE): New macro, for use in XSETPSEUDOVECTOR.
 (XSETTYPED_PVECTYPE): New macro, specifying the name of the size
 member.
 (XSETPVECTYPE): Rewrite in terms of new macro.
 (XSETPVECTYPESIZE): New macro, specifying both type and size.
 This is a bit clearer, and further avoids the possibility of
 undesirable aliasing.
 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR
 and XVECTOR_HEADER_SIZE.
 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
 since Lisp_Subr is a special case (no "next" field).
 (ASIZE): Rewrite in terms of XVECTOR_SIZE.
 (struct vector_header): New type.
 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
 object, to help avoid aliasing.
 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
 (SUBRP): Likewise, since Lisp_Subr is a special case.
 src/lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
 (struct Lisp_Hash_Table): Combine first two members into a single
 struct vector_header member.  All uses of "size" and "next" members
 changed to be "header.size" and "header.next".
 src/buffer.h (struct buffer): Likewise.
 src/font.h (struct font_spec, struct font_entity, struct font): Likewise.
 src/frame.h (struct frame): Likewise.
 src/process.h (struct Lisp_Process): Likewise.
 src/termhooks.h (struct terminal): Likewise.
 src/window.c (struct save_window_data, struct saved_window): Likewise.
 src/window.h (struct window): Likewise.
 src/alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
 src/buffer.c (init_buffer_once): Likewise.
 src/lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
 special case.
 src/process.c (Fformat_network_address): Use local var for size,
 for brevity.
 src/fns.c (vector): Remove; this old hack is no longer needed.
 src/bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

(ASIZE): Now contains previous implementation of XVECTOR_SIZE
instead of invoking XVECTOR_SIZE.

struct vector_header member.  All uses of "size" and "next" members
changed to be "header.size" and "header.next".

special case.
* process.c (Fformat_network_address): Use local var for size,
for brevity.

 adjust.
 src/msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
 to changes in oldXMenu/XMenu.h from 2011-04-16.
 (struct XMenu): Declare `help_text' `const char **'.
 src/xfaces.c <Qunspecified>: Make extern again.
 src/syntax.c: Include sys/types.h before including regex.h, as
 required by Posix.

Fix link errors in the Mac OS build that were caused by variables being marked as static that should not have been.

(FACE_SUITABLE_FOR_CHAR_P): Use it.
* font.c (font_close_object): Now static.
* font.h (font_close_object): Remove.
* fontset.c (FONTSET_OBJLIST): Remove.

* xfaces.c (face_at_string_position): Use
FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
since 0 is always ASCII.

* dispextern.h (ascii_face_of_lisp_face, free_realized_face):

This makes it easier for human readers (and static analyzers)
to see whether these variables are used from other modules.

so that it can be used in other C modules, use the new macro DEFUE.
* lisp.h (DEFINE_FUNC): New macro, with the old contents of DEFUN.
(DEFUN): Rewrite in terms of DEFINE_FUNC.  It now generates a
static function definition.  Use DEFUE if you want an extern one.

(Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
Remove decls, since these functions are now static.
