of Fsymbol_value.
(xstrdup): Moved to alloc.c.

(allocating_for_lisp): Variable removed.
(lisp_malloc): Block input around the calls to malloc and
mem_insert.

last, after all its members have been freed.

* emacs.c (main): Fix sense of no-loadup test.

inspection.  Beginnings of support for expensive internal consistency checks.

* config.in (ENABLE_CHECKING): Undef.

* lisp.h (struct interval): Replace "parent" field with a union of interval
pointer and Lisp_Object; add new bitfield to use as discriminant.  Change other
flag fields to bitfields.
(CHECK): New macro for consistency checking.  If ENABLE_CHECKING is defined and
the supplied test fails, print a message and abort.
(eassert): New macro.  Use CHECK to provide an assert-like facility.

* intervals.h (NULL_INTERVAL_P): Now applies only to real interval pointers;
abort if the value looks like a lisp object.
(NULL_INTERVAL_P, NULL_PARENT, HAS_PARENT, HAS_OBJECT, SET_PARENT, SET_OBJECT,
INTERVAL_PARENT, GET_INTERVAL_OBJECT, COPY_PARENT): Modify for new interval
parent definition.

* alloc.c (mark_interval_tree, MARK_INTERVAL_TREE, UNMARK_BALANCE_INTERVALS):
Update references that need an addressable lisp object in the interval
structure.
(die): New function.
(suppress_checking): New variable.

* intervals.c (interval_start_pos): Just return 0 if there's no parent object.

(appt-check): Convert min-to-app to a string before passing to
appt-disp-window-function or concat.
(appt-delete-window): Remove test for frame-root-window.
(appt-select-lowest-window, appt-convert-time): Simplify.

(byte-compile-file-form-autoload): Update
byte-compile-function-environment.

specially.

failed just delete its output.

(iso-iso2sgml-trans-tab, iso-sgml2iso-trans-tab): New variables.
(iso-iso2sgml, iso-sgml2iso): New functions.
(iso-cvt-define-menu): Fix some entries and use backquote for
clarity.

and earlier Emacs versions.

buffer and NEWTEXT.  Free allocated memory before signaling an
error.

of re_compile_fastmap and generalizing it a little bit so that it
can also just return whether a given (sub)pattern can match the empty
string or not.
(regex_compile): Use `analyse_first' to decide whether the loop-check
needs to be done or not for *, +, *? and +? (the loop check is costly
for non-greedy repetition).
(re_compile_fastmap): Delegate the actual work to `analyse_first'.

ISO-DATE.  If non-nil, return date in ISO 8601 format.

(enum re_opcode_t): Update description of succeed_n.
(PATFETCH): Always define.
(regex_compile): Use lookahead rather than PATUNFETCH (for repetition
operators, char classes, shy-groups and intervals).
Optimize special cases of intervals so as to only use succeed_n and
jump_n when really needed.
(re_compile_fastmap): Simplify handling of jump_n and succeed_n now
that we don't have to handle the special cases any more.
Simplify on_failure_jump handling as well.

(Vw32_charset_to_codepage_alist): Removed.
(Vw32_charset_info_alist): New variable.
(Qw32_charset_[ansi, default, symbol, shiftjis, hangul, gb2312,
chinesebig5, oem, easteurope, turkish, baltic, russian, arabic,
greek, hebrew, thai, johab, mac, unicode]): New symbols.
(x_produce_glyphs): Remove out of date #ifdef 0'd section. Replace
with TODO comment.
(w32_codepage_for_font): Use Vw32_charset_info_alist.
(syms_of_w32term): Remove Vw32_charset_to_codepage_alist.
Define Vw32_charset_info_alist and w32_charset symbols.

(mark_memory): Use it.
(SETJMP_WILL_LIKELY_WORK, SETJMP_WILL_NOT_WORK): New macros.
(setjmp_tested_p, longjmp_done): New variables.
(test_setjmp): New function.
(mark_stack) [!GC_SETJMP_WORKS]: Call test_setjmp.
(init_alloc): Initialize setjmp_tested_p and longjmp_done.
