    * frontend-passes.c (in_omp_workshare):  New variable.
    (cfe_expr_0):  Don't eliminiate common function if it would put
    the variable immediately into a WORKSHARE construct.
    (optimize_namespace):  Set in_omp_workshare.
    (gfc_code_walker):  Keep track of OMP PARALLEL and OMP WORKSHARE
    constructs.
