* configure (uintptr): New variable. Indicates whether unsigned

version of intptr_t is available and should be generated in config.h
as uintptr_t.

* eval.c (eval_init): New intrinsic functions floatp,
integerp, flo-str.

* gc.c (finalize): Handle FLNUM case. Rearranged
cases so that all trivially returning cases are
together.
(mark): Handle FLNUM case.

* hash.c (hash_double): New function.
(equal_hash): Handle FLNUM via hash_double.
(eql_hash): Likewise.

* lib.c: <math.h> is included.
(float_s): New symbol variable.
(code2type, equal): Handle FLNUM case in switch.
(integerp): New function; does the same thing
as integerp before.
(numberp): Returns t for floats.
(flo, floatp, flo_str): New functions.
(obj_init): Initialize new float_s variable.
(obj_print, obj_pprint): Handle FLNUM case in switch.
Printing does not work yet; needs work in stream.c.

* lib.h (enum type): New enumeration FLNUM.
(struct flonum): New struct type.
(union obj): New member, fl.
(float_s, flo, floatp, integerp, flo_str): Declared.

* parser.l (FLO): New token pattern definition.
Scans to a NUMBER token.
Corrected uses of yylval.num to yylval.val.

* parser.y (%union): Removed num member from yystype.
