ANSI CL support

[Raymond T. <toy...@gm...>]

A friend pointed this out to me:

(apropos "-ANSI") ->
*COERCE-FIXNUM-CHAR-ANSI*                  variable
*FLOATING-POINT-CONTAGION-ANSI*            variable
*FLOATING-POINT-RATIONAL-CONTAGION-ANSI*    variable
*LOOP-ANSI*                                variable
*MERGE-PATHNAMES-ANSI*                     variable
*PARSE-NAMESTRING-ANSI*                    variable
*PHASE-ANSI*                               variable
*PRINT-EMPTY-ARRAYS-ANSI*                  variable
*PRINT-PATHNAMES-ANSI*                     variable
*PRINT-SPACE-CHAR-ANSI*                    variable
*PRINT-UNREADABLE-ANSI*                    variable
*SEQUENCE-COUNT-ANSI*                      variable

The ANSI CL spec is now almost 20 years old and hasn't changed since
then. I didn't check to see what all of variables actually do, but
isn't it time to make these default to T? Or at least some of them?
