	* configure.in: add G_DISABLE_SINGLE_INCLUDES and
	ATK_DISABLE_SINGLE_INCLUDES to CPPFLAGS.

	* atk/atk.h: define __ATK_H_INSIDE__ around including all other
	headers.

	* atk/atk*.h: add single-include guards that #error out if
	ATK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
	included individually. Use G_BEGIN_DECLS/G_END_DECLS in all files.

	* atk/Makefile.am: define ATK_COMPILATION while building ATK.
	Add single-include guards to the generated atk-enum-types.h too.
