forked from AuroraMiddleware/gtk
should break on Unix/X11. Win32 merge and general portability stuff: * acconfig.h,configure.in: Check for <sys/time.h>. * gdk/win32: New directory (actually, been there for a while). * gtk/fnmatch.c: Include <glib.h> for G_DIR_SEPARATOR, WIN32 and NATIVE_WIN32, and use these. Always case fold on Win32. No backslashed escapes on native Win32. * gtk/{gtk.def,makefile.msc}: New files. * gtk/Makefile.am: Add above new files. * gtk/{gtkaccelgroup,gtkbindings}.c: Include <string.h> instead of <strings.h>. * gtk/{gtkcalendar,gtkitemfactory,gtkpreview,gtkrc}.c: Include config.h. Protect inclusion of <sys/param.h>, <sys/time.h>, and <unistd.h> appropriately. * gtk/gtkdnd.c: Merge in Win32 version (which doesn't do much). Use ABS() (from <glib.h>) instead of abs(). * gtk/gtkfilesel.c: Moved Win32-specific includes after inclusion of gtk (and thus glib) headers, so that WIN32 will be defined. With MS C, include <direct.h> for mkdir prototype. * gtk/gtkitemfactory.c (gtk_item_factory_callback_marshal): Add some casts, needed by MS C. * gtk/{gtklayout,gtkplug}.c: Merge in Win32 version (which isn't implemented). * gtk/gtkmain.c: Include gdk/gdkx.h for GDK_WINDOWING. Include <X11/Xlocale.h> only on X11 platform, otherwise <locale.h>. Use G_SEARCHPATH_SEPARATOR_S and g_module_build_path. * gtk/gtkmain.h: Mark variables for export/import on Win32. * gtk/gtkrange.c (gtk_range_motion_notify): Set mods also in case the event is not a hint, or its window is not the slider. Needed on Win32, at least. * gtk/gtkrc.c: Include config.h and gdk/gdkx.h. Use <locale.h> unless on X11. Skip \r chars, too. Use G_DIR_SEPARATOR and G_SEARCHPATH_SEPARATOR(_S). Use g_path_is_absolute. On Win32, use a subdirectory of the Windows directory as gtk system configuration directory. * gtk/gtkselection.c: No chunks on Win32. * gtk/gtksocket.c: Not implemented on Win32. * gtk/gtkthemes.c (gtk_theme_engine_get): Use g_module_build_path. * gtk/makeenums.h: Include gdkprivate.h after gdk.h. * gtk/testrgb.c: Use dynamically allocated buffer. Use GTimers.
