this is program 'testb' in the following. Program 'testa' is the
previous one involving 'malloc'.

Using 'gcc' as done by meissner@osf.org, the following results. You
can pick up the tar file for building this (heavily modified) version
of 'gcc' from foobar.colorado.edu:pub/Gnu-For-Pmax. Be warned that
that 'gcc' -O3 and -O2 optimization produces code about 10-20% slower
than Mips 'cc' (1.31). I do not know how it compares to the mips 2.x
suite.
