Actually it's printf.. (was Re: Another C compiler bug)

|hi = 9.500000e-07   hi = 5.000001e-07	hi = 5.000001e-07  hi = 5.000001e-07
|lo = 9.500000e-07   lo = 5.000000e-07  lo = 5.000000e-07  lo = 5.000000e-07

On an ESV (MIPS R3000, ES/os 1.3, MIPS cc 2.1) I obtained the same
numbers as the 68k, sparc and vax/vms.  I suspect it is the libraries
in Ultrix as well.
