Extended Description

I've compiled several standard linear algebra matrix products,
using the transposed-right-argument algorithm, and array sizes of 400x400.
On my AMD platform here, I get the following timings:
Source code     Compiler invocation    User time
ipdd.sac        sac2c -O3              7.5  sec
matmul.sac(demo)sac2c -O3              6.5  sec
ipdd.f          g77                    1.69 sec
ipdd.wif        APL+Win interpreter    4.3  sec
So, as you can see, sac remains far behind in performance here.
I have not,as yet, made any attempt to examine the reasons for the
poor performance.
