patch which add the private clause on i

When investigating a test failure in the openmp testsuite, we found that the
test target-31.c exhibit a wrong behavior at -O0.

This is due to a missing private clause on the i variable.  At higher
optimization levels, the i variable is optimized out which makes the wrong
behavior disappear.

In attachment, a patch adding the missing private clause.
