graph (2.4.1) gets SIGFPE on Alpha; -mieee fixes it

[Mike Coleman]

Package: plotutils
Version: 2.4.1-7

On an alpha box, graph gets a SIGFPE on some input.  The data file used below
contains most of the whole numbers from 0 to 12000, one per line (some
missing).  I remade this package with the '-mieee' flag, and that seemed to
stop the SIGFPE.
