    	Port to Windows, initial commit.
    
    	* configure.in: Bump version to 2.11.0 to distinguish from the
    	gnome-2-10 branch. Define Automake conditional OS_WIN32. Depend on
    	GLib 2.6 so that we can use the gstdio.h wrappers to make
    	non-ASCII path names work better on Win32.
    
    	* libgnome-zip.in: New file, to build libgnome distribution for
    	Win32.
    
    	* Makefile.am
    	* configure.in: Distribute and expand it.
    
    	* configure.in
    	* libgnome/libgnome-2.0.pc.in
    	* libgnome/gnome-init.c
    	* libgnome/gnome-open.c: Try to manage without gnome-vfs on Win32,
    	at least for now.
    
    	* libgnome/gnome-config.c
    	* libgnome/gnome-init.c
    	* libgnome/gnome-score.c
    	* libgnome/gnome-triggers.c: Use gstdio wrappers. Use GLib
    	pathname manipulation functions where applicable. Use gdir
    	functions. Accept both the canonical backslash and slash as path
    	compinent separators on Win32.
    
    	* libgnome/dllmain.c: New file. Contains the Win32 DLL entry
    	point, which is used here to implement installation location
    	independence. Sets up run-time paths to libdir, sysconfdir etc.
    
    	* libgnome/libgnome-private.h: New file. On Win32 undefs the
    	compile-time definitions of directory pathnames and defines them
    	to point to the run-time ones instead.
    
    	* libgnome/gnome-init.c
    	* libgnome/gnome-program.c
    	* libgnome/gnome-score.c: Include libgnome-private.h.
    
    	* libgnome/gnome-exec.c (gnome_execute_async_with_env_fds,
    	gnome_prepend_terminal_to_vector): Just stub out with g_warning()
    	on Win32 for now. Implement later if needed.
    
    	* libgnome/gnome-program.c: Dummy getuid/geteuid/getgid/getegid
    	definitions for Win32. No setuid or setgid concept.
    
    	* libgnome/gnome-score.c (log_score): Use ftruncate() on Unix,
    	_chsize() on Win32.
    	(gnome_score_child_thread, gnome_score_init): Use a thread on
    	Win32 where we have no fork().
    	(gnome_score_log): No setgid concept on Win32, no need to check.
    
    	* libgnome/gnome-triggers.c: Use g_spawn_sync() on Win32.
    
    	* libgnome/gnome-url.c (gnome_url_show_with_env): Use
    	ShellExecute() on Win32.
    
    	* libgnome/gnome-util.c (gnome_util_user_shell): Look for cmd.exe
    	or command.com on Win32.
    
    	* schemas/Makefile.am (install-data-local): Work around MSYS
    	feature on Win32. It converts environment variables that look like
    	search paths into the Windows format (with semicoon
    	delimiters). The GCONFIG_CONFIG_SOURCE would get mangled, so we
    	have to run gconftool-2 through temporary .bat file.
