In gomp-4_0-branch, we've tried to consolidate the parsing all of the clauses of the form
foo (int-expression) into a single c*_parser_omp_positive_int_clause function. At the time, such clauses included num_gangs, num_workers, vector_length and num_threads. Looking at OpenMP 4.5, there are additional candidates for this function, specifically num_tasks, grainsize, priority and hint. With that in mind, parser support for all of the aforementioned clauses is already present in trunk, so I'll revert these change in gomp-4_0-branch since they add no functionality. We might revisit a similar patch if OpenACC adds new clauses of this form in the future. I've applied this patch to gomp-4_0-branch. Cesar
