	* Makefile.in (LIBDECNUMBER_DIR, LIBDECNUMBER, LIBDECNUMBER_SRC
	LIBDECNUMBER_CFLAGS): New macros for libdecnumber.
	(INTERNAL_CFLAGS_BASE): Add LIBDECNUMBER_CFLAGS in.
	(INSTALLED_LIBS): Add -ldecnumber in.
	(CLIBS): Add LIBDECNUMBER in.
	(decimal128_h, decimal64_h, decimal32_h): New macros for decimal
	headers.
	(dfp_h): New macros for decimal floating point.
	(dfp.o): New target.
	(COMMON_OBS): Add dfp.o in.
	(c-exp.o): Add dfp_h as dependency.
	(valprint.o): Add dfp_h as dependency.
	(value.o): Add dfp_h as dependency.
	* dfp.h: New header file for decimal floating point support in
	GDB.
	* dfp.c: New source file for decimal floating point support in
	GDB.  Implement decimal_from_string and decimal_to_string based
	on libdecnumber API.
	* configure.ac: Add AC_C_BIGENDIAN test.
	* config.in, configure: Regenerate.
