headers for buffer_defaults and buffer_local_symbols.
Reported by Juanma Barranquero <lekktu@gmail.com>.

* src/lisp.h (enum pvec_type): Use fewer bits.
(PSEUDOVECTOR_SIZE_BITS): New constant.
(PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
(XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
change in pvec_type.
(PSEUDOVECTOR_TYPEP): New macro.
(TYPED_PSEUDOVECTORP): Use it.
* src/fns.c (internal_equal): Adapt code to extract pvectype.
* src/emacs.c (gdb_pvec_type): Update type.
* src/alloc.c (PSEUDOVECTOR_NBYTES): New macro.
(VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
(VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
(SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
(sweep_vectors): Use it.  Use local var `total_bytes' instead of
abusing vector->header.next.nbytes.
(live_vector_p): Use PVEC_TYPE.
(mark_object): Adapt code to extract pvectype.  Use switch.

Tighten new eassert a bit.

optimization level.
* configure.in: If --enable-gcc-warnings, disable
-Wunsafe-loop-optimizations for -O1 optimization level.
* src/doprnt.c (doprnt): Change type of tem to int, initialize
to avoid compiler warning.  Add eassert.
* src/search.c (simple_search): Initialize match_byte to avoid
compiler warning.  Add eassert.

Without this change, for example, large hscroll values would
mess up Emacs's display on Fedora 15 x86, presumably due to
overflows in int calculations in the display code.
Also, if buffers had long lines, Emacs would freeze.
* window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
(set_window_hscroll): New function, containing the old guts of
Fset_window_hscroll.  Return the clipped value.
(Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
This avoids the need to check against PTRDIFF_MAX.

Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
since GCC 4.4.6 issues a bogus warning for them.

* fileio.c (Ffile_newer_than_file_p):
* lread.c (Fload): Use full timestamp resolution of files,
not just the 1-second resolution, so that files that are only
slightly newer still count as newer.
* fileio.c (Ffile_newer_than_file_p): Don't assume file
timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.

(special_mtime): New function.
(Finsert_file_contents, Fverify_visited_file_modtime):
Use it to set special mtime values consistently.

(mark_object): Use it.  Adjust marking of misc objects
and related comments.

wrapper that is not needed because the wrapped code is a no-op (zero
machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.

(mark_object): Add comment.  Reorganize marking of vector-like
objects.  Use CHECK_LIVE for all vector-like ojects except buffers
and subroutines when GC_CHECK_MARKED_OBJECTS is defined.  Avoid
redundant calls to mark_vectorlike for bool vectors.

 msdos/mainmake.v2 (bootstrap-clean): Do a maintainer-clean in lib, not
 bootstrap-clean (which doesn't exist).
 msdos/inttypes.h (PRIuMAX) [__DJGPP__ < 2.04]: Define to "llu".
 msdos/sedleim.inp (MKDIR_P): Edit to DOS "md" command.
 msdos/sed1v2.inp: (LIB_CLOCK_GETTIME): Edit to empty.
 Remove lines that invoke PAXCTL.
 (clean): Fix recipe not to run Unixy shell commands.
 msdos/sed2v2.inp (GETTIMEOFDAY_TIMEZONE): Edit to 'struct timezone'.
 (HAVE_STRNCASECMP): Edit to 1.
 msdos/sed3v2.inp (LIB_CLOCK_GETTIME): Edit to empty.
 (C_SWITCH_SYSTEM): Add "-I../msdos".
 msdos/sedlibmk.inp (GNULIB_GETTIMEOFDAY, GNULIB_PSELECT)
 (GNULIB_SELECT, HAVE_STRUCT_TIMEVAL, HAVE_SYS_SELECT_H)
 (HAVE_SYS_TIME_H, NEXT_AS_FIRST_DIRECTIVE_SYS_SELECT_H)
 (NEXT_AS_FIRST_DIRECTIVE_SYS_TIME_H, NEXT_SYS_SELECT_H)
 (NEXT_SYS_TIME_H, REPLACE_GETTIMEOFDAY, REPLACE_PSELECT)
 (REPLACE_STRUCT_TIMEVAL): Edit to appropriate values.
 (BUILT_SOURCES): Edit out sys/select.h and sys/time.h.
 (mostlyclean-local, distclean-generic): Fix recipe not to run
 Unixy shell commands.

 src/sysselect.h [DOS_NT]: Don't include sys/select.h.
 src/s/ms-w32.h (select, pselect): Don't define here, they are
 defined in sysselect.h
 src/sysselect.h (pselect) [!HAVE_PSELECT]: Redirect to sys_select.
 src/sysdep.c: Don't include dos.h and dosfns.h.
 src/process.c (sys_select):
 src/msdos.c (sys_select): Accept one more argument and ignore it.
 src/msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
 adapt data types and code to that.
 src/dosfns.c:
 src/msdos.c (gettime, settime): Define away the prototypes in dos.h,
 which clashes with the gnulib function of the same name.

 lisp/emacs-lisp/timer.el (timer-until): Subtract results of
 float-time, instead of taking float-time of the result of
 time-subtract, since float-time signals an error for negative time
 arguments.

(font_prop_validate_style): Add type checks for values in
font_style_table.

argument.
* character.c, charset.c, menu.c, process.c, window.c: Adjust all
uses.

 src/xdisp.c (try_window_id): Undo last change.  'int' is wide 
 enough to hold vertical pixel positions on screen.

 src/w32.c (getwd): Adjust commentary about startup_dir.
 (init_environment): Always call sys_access, even in non-MSVC
 builds.  Don't chdir to the directory of the Emacs executable.
 This undoes code from 1997 which was justified by the need to
 "avoid conflicts when removing and renaming directories".  But its
 downside was that every relative file name was being interpreted
 relative to the directory of the Emacs executable, which can never
 be TRT.  In particular, it broke sys_access when called with
 relative file names.
 (sys_access): Map GetLastError to errno.

* src/window.h (struct window): Change type of 'fringes_outside_margins'

* nsterm.m: Likewise.

overflow when requested scroll falls outside ptrdiff_t range.

'last_modified' and 'last_overlay_modified' to EMACS_INT.
Adjust users accordingly.
* xdisp.c (try_cursor_movement): Replace type check with eassert.
* window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
from EMACS_INT to ptrdiff_t.
(make_window): Omit redundant initialization.

'sequence_number' from Lisp_Object to int.
