Nice example.  It's not even specific to ecl.  CMUCL and clisp print the
same thing.

The difference between ecl on Solaris/sparc and Solaris/x86 could very
well be the floating-point units or the routines used to compute cl:asinh.

(format nil "~vf" 17 (asinh 1d0))

produces a leading 0 on Solaris with cmucl, but there's no leading zero
on Solaris clisp.  The number value of (asinh 1d0) is slightly different
too.
