(abort): Return type is now ABORT_RETURN_TYPE.
(main): Always invoke init_signals, even if POSIX_SIGNALS is not
defined.
(syms_of_emacs): messages-locale -> system-messages-locale,
previous-messages-locale -> previous-system-messages-locale,
time-locale -> system-time-locale,
previous-time-locale -> previous-system-time-locale.
* gmalloc.c (PP, __ptr_t): Assume ANSI C if STDC_HEADERS is defined.
(const): Do not define; that's config.h's job.
(<limits.h>): Include if HAVE_LIMITS_H is defined.
(CHAR_BIT): Move test for definedness outside of limits.h condition.
(<stddef.h>): Include if STDC_HEADERS is defined.
(FREE_RETURN_TYPE): New macro.
(free): Return type is now FREE_RETURN_TYPE.
* lisp.h (synchronize_system_time_locale): Renamed from
synchronize_time_locale. All uses changed.
(synchronize_system_messages_locale): Likewise, from
synchronize_messages_locale.
* process.c (sys_siglist): Remove.

(Fforward_comment, scan_lists, scan_sexps_forward)
(Fparse_partial_sexp): Add support for nested comments.
(forw_comment): New subroutine used in them.
that ends a comment, when moving forward.
(Fbackward_prefix_chars): Return immediately if point is at BEGV.
(prev_char_comend_first): New function.
(back_comment): Use that. Carefully update syntax table position
for each character that is fetched.
(Fforward_comment): Likewise.
(scan_lists): Likewise.
(prev_char_comstart_first): New function.
(scan_sexps_forward): Make INC_FROM do UPDATE_SYNTAX_TABLE_FORWARD.
Delete the explicit calls to UPDATE_SYNTAX_TABLE_FORWARD.
Also set prev_from_syntax (new local var). Test that in the loop,
instead of fetching syntax of the previous char.
(Fforward_comment): Always use both FROM and FROM_BYTE to set point.
Use dec_bytepos not DEC_POS.
(scan_lists): Handle unibyte buffers when decrementing temp_pos.
(INC_FROM): Use INC_BOTH.
(inc_bytepos, dec_bytepos): In unibyte mode, just increment bytepos.
(find_defun_start): Additional arg POS_BYTE.
Save final byte pos in find_start_value_byte.
(find_start_value_byte): New variable.
(Fforward_comment): Scan by bytes and chars.
(Fbackward_prefix_chars): Scan by bytes and chars.
(scan_words, scan_sexps_forward): Scan bytes as well as chars.
