Derrick Cole <cole@elvis.concert.net> was "exposed to c-lisp for a grand

This is due to the fact that on Sparc, CLISP uses the floating format
prescribed by the hardware for DOUBLE-FLOATs. It differs from CLISP's soft
floats. Consider the testsuite to have succeeded.

Don't invoke lisp.run without arguments (except on Atari) - it contains
only one half of clisp. Not even DEFUN or SETF. And floating point numbers
are printed in binary because floatpri.lsp has not been loaded...
