aa220473ba * Add native support for long double data type.

	for FLOAT use type determined by parse_number.  Add production for
	"long double" data type.
	* (parse_number):  Use sscanf to parse numbers as float, double or
	long double depending upon the type of typed_val_float.dval.  Also
	allow user to specify `f' or `l' suffix to explicitly specify
	float or long double constants.  Change typed_val to
	typed_val_int.

	"double" keyword.

	DOUBLEST.
	* m2-exp.y f-exp.y (%union):  dval becomes type DOUBLEST.

	DOUBLEST.
	* valarith.c (value_binop):  Change temp variables v1, v2 and v to
	type DOUBLEST.  Coerce type of result to long double if either op
	was of that type.
	* valops.c (value_arg_coerce):  If argument type is bigger than
	double, coerce to long double.
	* (call_function_by_hand):  If REG_STRUCT_HAS_ADDR is defined, and
	arg type is float and > 8 bytes, then use pointer-to-object
	calling conventions.
	* valprint.c (print_floating):  Arg doub is now type DOUBLEST.
	Use appropriate format and precision to print out floating point
	values.
	* value.h:  Fixup prototypes for value_as_double,
	value_from_double, and unpack_double to use DOUBLEST.
	* values.c (record_latest_value):  Remove check for invalid

        * valops.c (value_struct_elt): when name and args match does not

        memeber method and args. This probably will not happen with new
        version of g++, but it does happen in old g++ and cause gdb error.

Thomas Lord
199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

	Change sizeof (float) to 4 and sizeof (double) to 8 (those are always
