* coding.c (min, max):
* font.c (MAX):
* unexhp9k800.c (min):
* unexw32.c (min, max): Use definitions from lisp.h.
* regex.c (MAX, MIN) [!emacs]: Define own max and min as such.
Adjust users.
* gmalloc.c (min): Tiny style change.

* src/gmalloc.c [CYGWIN]: Adapt to change in sheap.c.

* src/sheap.c (bss_sbrk_buffer_end): Cast to void *.
(bss_sbrk_buffer_beg): New variable.  Use it...
* src/gmalloc.c (ALLOCATED_BEFORE_DUMPING) [CYGWIN]: ...here, to fix
  incorrect definition.

* src/gmalloc.c: Don't include <stdlib.h>.  Declare system malloc and
friends before defining hybrid_malloc and friends if HYBRID_MALLOC
is defined.  (Bug#18368)

dumping and the system malloc after dumping.  (Bug#18222)

* configure.ac (HYBRID_MALLOC): New macro; define to use gmalloc
before dumping and the system malloc after dumping.  Define on Cygwin.
* src/conf_post.h (malloc, realloc, calloc, free) [HYBRID_MALLOC]:
Define as macros, expanding to hybrid_malloc, etc.
(HYBRID_GET_CURRENT_DIR_NAME): New macro.
(get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]: Define as
macro.
* src/gmalloc.c: Set up the infrastructure for HYBRID_MALLOC, with a
full implementation on Cygwin.  Remove Cygwin-specific code that
is no longer needed.
(malloc, realloc, calloc, free, aligned_alloc) [HYBRID_MALLOC]:
Redefine as macros expanding to gmalloc, grealloc, etc.
(DUMPED, ALLOCATED_BEFORE_DUMPING) [CYGWIN]: New macros.
(get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]: Undefine.
(USE_PTHREAD, posix_memalign) [HYBRID_MALLOC]: Don't define.
(hybrid_malloc, hybrid_calloc, hybrid_free, hybrid_realloc)
[HYBRID_MALLOC]:
(hybrid_get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]:
(hybrid_aligned_alloc) [HYBRID_MALLOC && (HAVE_ALIGNED_ALLOC ||
HAVE_POSIX_MEMALIGN)]: New functions.
* src/alloc.c (aligned_alloc) [HYBRID_MALLOC && (ALIGNED_ALLOC ||
HAVE_POSIX_MEMALIGN)]: Define as macro expanding to
hybrid_aligned_alloc; declare.
(USE_ALIGNED_ALLOC) [HYBRID_MALLOC && (ALIGNED_ALLOC ||
HAVE_POSIX_MEMALIGN)]: Define.
(refill_memory_reserve) [HYBRID_MALLOC]: Do nothing.
* src/sysdep.c (get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]:
Define as macro, expanding to gget_current_dir_name, and define
the latter.
* src/emacs.c (main) [HYBRID_MALLOC]: Don't call memory_warnings() or
malloc_enable_thread().  Don't initialize malloc.
* src/lisp.h (NONPOINTER_BITS) [CYGWIN]: Define (because GNU_MALLOC is
no longer defined on Cygwin).
(refill_memory_reserve) [HYBRID_MALLOC]: Don't declare.
* src/sheap.c (bss_sbrk_buffer_end): New variable.
* src/unexcw.c (__malloc_initialized): Remove variable.
* src/ralloc.c: Throughout, treat HYBRID_MALLOC the same as
SYSTEM_MALLOC.
* src/xdisp.c (decode_mode_spec) [HYBRID_MALLOC]: Don't check
	Vmemory_full.

This documents the C API, and helps GCC generate a bit better code.
* conf_post.h (ATTRIBUTE_MALLOC, ATTRIBUTE_ALLOC_SIZE)
(ATTRIBUTE_MALLOC_SIZE): New macros.
* gmalloc.c (malloc, realloc, calloc):
* gtkutil.h (malloc_widget_value):
* lisp.h (ralloc, r_re_alloc, xmalloc, xzalloc, xrealloc, xnmalloc)
(xnrealloc, xstrdup, xlispstrdup, record_xmalloc):
Use them.

* src/gmalloc.c (aligned_alloc): Clarify the code by making `adj'
represent the actual adjustment needed for alignment.
