Extended Description

When compiling the attached program with svn rev 15291, optimisation cycles stop
after 3 loops.
but if compiled with rev 15292, the following command
"sac2c ScalarArith.sac -bopt:cyc -maxoptcyc 50"
will run through all 50 cycles.
The program is taken direktly from ScalarArith.sac.
