* src/w32common.h: Rename OS_* to OS_SUBTYPE__*, as w32 API
headers started defining OS_NT, which breaks the use of the
enumeration. All users changed. (Bug#48303)
* src/w32fns.c (w32_version_string) [WINDOWSNT]: New function.
* src/w32common.h (w32_version_string) [WINDOWSNT]: Add prototype.
* src/editfns.c (init_editfns) [WINDOWSNT]: Produce a non-nil
string with the OS version.
* src/comp.c (init_gccjit_functions): Use LOAD_DLL_FN_OPT macro to
load gcc_jit_version_major, gcc_jit_version_major and
gcc_jit_version_patchlevel.
* src/w32common.h (LOAD_DLL_FN_OPT): Add macro optionally load a
function from a DLL.
* src/hbfont.c: New file, with code moved from w32uniscribe.c
and renamed/modified as appropriate.
* src/w32uniscribe.c: Move to hbfont.c DEF_DLL_FN and macro
definitions for HarfBuzz functions used in hbfont.c
(load_harfbuzz_funcs): Move loading of HarfBuzz functions used
by hbfont.c to hbfont.c:hbfont_init_w32_funcs, and call that
function from here.
(syms_of_w32uniscribe_for_pdumper): Fill the 'shape' and
'combining_capability' members with hbfont.c function names.
* src/w32common.h (hbfont_init_w32_funcs) [HAVE_HARFBUZZ]: Add
prototype.
* src/font.h (hbfont_shape, hbfont_combining_capability)
[HAVE_HARFBUZZ]: Add prototypes.
* src/Makefile.in (SOME_MACHINE_OBJECTS): Add hbfont.o.
* configure.ac (FONT_OBJ): Add hbfont.o if HAVE_HARFBUZZ.
Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
src/w32fns.c: Remove prototype of atof.
(syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
builds.
(file_dialog_callback): Declared UINT_PTR.
src/w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
with 64-bit builds.
src/w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
(FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
defined.
