	Port to Windows:

	* gconf-zip.in: New file, script to build zipfile-based
	distribution for Windows.

	* Makefile.am
	* configure.in: Distribute and expand it.

	* configure.in: Check for Win32, Define automake conditional
	OS_WIN32. Force shared library (DLL) build on Windows. Check for
	some more headers and functions.

	* */*.c: Conditionalize on HAVE_SYSLOG_H, HAVE_SYS_WAIT_H,
	HAVE_GETUID, HAVE_FSYNC, HAVE_FCHMOD, HAVE_SIGACTION, F_GETFD,
	FD_CLOEXEC, F_SETLK, SIGBUS, SIGPIPE, SIGHUP, SIGUSR1, and ELOOP.

	* backends/Makefile.am: Explicitly link with INTLLIBS.

	* backends/markup-tree.c (save_tree): Can't rename or remove open
	files on Win32.

	* backends/xml-backend.c: Don't use G_MODULE_EXPORT on Win32. If
	we use it, only the functions thus marked will be exported, and
	xml-test uses also other ones. Instead rely on the auto-export
	feature.

	* gconf/Makefile.am: Pass -DPREFIX=$(prefix). Include dllmain.c
	on Win32.

	* gconf/dllmain.c: New file. Used for installation location
	independence.
	(DllMain) DLL entry point. Automatically called when the DLL is
	attached to a process. Deduce the run-time installation location
	and construct run-time pathnames.
	(gconf_win32_replace_prefix): New funcion. Replaces a
	configure-time prefix in a pathname with the corresponding
	end-user run-time installation prefix.

	* gconf/gconf-internals.c (gconf_win32_get_home_dir): New
	function, returns the home directory with forward
	slashes. Guaranteed to return non-NULL, unlike GLib's
	g_get_home_dir().
	(get_variable, gconf_get_daemon_dir): Use gconf_win32_get_home_dir().
	(gconf_load_source_path): Use gconf_win32_replace_prefix().
	(create_new_locked_file, open_empty_locked_file,
	gconf_release_lock): Use _sopen() to open file with locking on
	Win32.
	(close_fd_func): Not used on Win32, where there is no FD_CLOEXEC,
	and a gspawn child setup function is run in the parent process
	anyway.

	* gconf/gconf-internals.h: mkdir() takes only one parameter on
	Win32. S_IRWX{U,G,O} aren't in mingw's sys/stat.h. Use run-time
	installation prefix instead of configure-time. Redefine the
	GCONF_*DIR macros to refer to the variables from the dllmain.c
	file. Use NUL: on Windows instead of /dev/null.

	* gconf/gconf-sanity-check.c
	* gconf/gconftool.c: Use POPT_AUTOHELP.

	* gconf/gconf.c: Use g_get_current_time() instead of gettimeofday().

	* gconf/gconfd.c (gconf_server_load, get_log_names): Use
	gconf_win32_get_home_dir().
	(signal_handler): If we don't HAVE_SIGACTION, use signal(), and
	re-arm the signal handler.
	(test_safe_tmp_dir): Can't open() a directory on Win32.
	(get_log_names): Use g_build_filename() instead of
	gconf_concat_dir_and_key() on all platforms.
