Tor Lillqvist 2decafb544 Port to Windows, initial commit: 
2005-04-29  Tor Lillqvist  <tml@novell.com>

	Port to Windows, initial commit:

	* configure.in: Check for Win32, define Automake conditional
	OS_WIN32. Check for regexec() perhaps in separate -lregex, define
	REGEX_LIBS if so. Require glib-2.0 >= 2.6 (and thus also gtk+-2.0
	>= 2.6) so that we can use the gstdio wrappers for full support of
	non-ASCII filenames on Win32. Don't use -D_REENTRANT on Win32, has
	ne special meaning.

	* gal.pc.in: Require gtk+-2.0 >= 2.6 also here for consistency.

	* gal-zip.in: New file, used to build zipfile format distribution
	of gal for Win32.

	* configure.in
	* Makefile.am: Add gal-zip(.in).

	* */Makefile.am
	* */*.c: Harmonize -I and #include conventions. (Of course, this
	hasn't anything to do with Windows porting as such, I just got
	carried away...) Use only -I$(top_srcdir). Use paths to gal
	headers staring with "gal", except for headers from the same
	directory as the .c file, which are included as such. Include all
	gal headers using doublequotes. Sort #includes and remove
	duplicates and obvious redundancies. Include config.h first
	without any HAVE_CONFIG_H, then system headers, then other GNOME
	lib headers, than gal's own headers. Just include gtk.h instead of
	separate gtk*.h headers. Don't include gi18n.h, include e-i18n.h
	to use e_gettext() consistently.

	* gal/Makefile.am: Use -no-undefined on Win32 so that libtool
	agrees to build a shared library. Because of the bidirectional
	dependency between libgal and libgal-a11y we can build libgal-a11y
	sanely as a shared library on Win32, so we don't install any
	separate libgal-a11y at all. So, on Win32, link the stuff that
	goes into libgal-a11y also into libgal. Link with REGEX_LIBS.

	* gal/a11y/Makefile.am: See above. Just build a dummy static
	libgal-a11y on Win32 (can't convince Automake not to build the
	library at all on one platform using Automake ifdef,
	apparently). Then (this is a gross hack) explicitly remove the
	library after installation in the install-data-local rule.

	* gal/e-table/Makefile.am
	* gal/e-table/e-table-config.c: Rename ETABLE_GLADEDIR to
	GAL_GLADEDIR for consistency.

	* gal/e-table/e-cell-date.c: No localtime_r() in Microsoft's C
	library, but its localtime() *is* thread-safe.

	* gal/e-table/e-cell-text.c
	* gal/e-table/e-cell-tree.c
	* gal/e-table/e-cell-vbox.c
	* gal/e-text/e-text.c
	* gal/widgets/e-unicode.c: Remove unnecessary inclusion of gdkx.h.

	* gal/e-table/e-cell-tree.c (ect_realize): Instead of the Xlib
	macro None (whose value is zero), use the corresponding
	zero-valued enums from the appropriate GDK type.

	* gal/e-table/e-table-config.c
	* gal/e-table/e-table-field-chooser.c
	* gal/menus/gal-define-views-dialog.c
	* gal/menus/gal-view-instance-save-as-dialog.c
	* gal/menus/gal-view-new-dialog.c
	* gal/widgets/e-categories-master-list-array.c
	* gal/widgets/e-categories-master-list-dialog.c
	* gal/widgets/e-categories.c: Use g_build_filename() to construct
	pathnames at run-time instead of compile-time. On Windows the
	macros GAL_GLADEDIR and GAL_IMAGESDIR expand to function calls, in
	order to support installing in a freely chosen location.

	* gal/e-table/e-table-item.c
	* gal/e-table/e-cell-vbox.c: Instrad of the Xlib GrabSuccess, use
	GDK_GRAB_SUCCESS (which has the same value).

	* gal/e-table/e-table-specification.c (e_table_specification_load_from_file)
	* gal/e-table/e-table.c (e_table_load_specification)
	* gal/e-table/e-tree-table-adapter.c (open_file)
	* gal/menus/gal-view-instance.c (load_current_view)
	* gal/menus/gal-view-instance.c (load_current_view): On Win32,
	convert filename to the locale character set before passing to
	xmlParseFile() which doesn't use UTF-8 filenames. Use gstdio
	wrappers.

	* gal/util/Makefile.am: Define GAL_PREFIX as $prefix. Define
	GAL_LOCALEDIR, GAL_GLADEDIR and GAL_IMAGESDIR also here for
	e-win32-reloc.c. Include e-win32-reloc.c on Win32.

	* gal/util/e-iconv.c (e_iconv_init): Use g_win32_getlocale() on
	Windows.

	* gal/util/e-util.c
	* gal/util/e-xml-utils.c: Use g_mkstemp() instead of non-portable
	mkstemp(). Use GLib pathname manipulation functions. Use gstdio
	wrappers.

	* gal/util/e-util-private.h: New file. Contains just Win32 bits
	for now that redefine the directory names from the Makefile as
	functions calls.

	* gal/util/e-win32-reloc.c: New file. Contains a minimal DllMain()
	and functions to support freely chosen installation location on
	Windows.

	* gal/util/e-xml-utils.c: No fsync() in the Microsoft C library.

	* gal/windgets/Makefile.am: Add -I$(top_srcdir)/gal for
	consistency with the sibling Makefile.am files.

	* gal/widgets/e-canvas.c: Instead of the Xlib AlreadyGrabbed, use
	GDK_GRAB_ALREADY_GRABBED.
