The following change fixes the comment. Tested with "make" on
x86_64-unknown-linux-gnu. I'll install this as "obvious" tomorrow if
nobody comments on the patch.

Both of these requirements are easily satisfied. The largest target

Note that the decimal string conversion routines are sensitive to
rounding errors. Since the raw arithmetic routines do not themselves
