Running this with g77-3.1 under gdb on cygwin, it's hanging in the final
do{..}while(s>s0) in z_log(). Attempting to display the values of local
variables crashes gdb. If this awkward looking code is to be preserved, it
looks like the loop ending condition needs to change to something like
while(s > s0 +DBL_EPSILON).
