* 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.
