I guess we could move the loop body from c_parser_compound_statement_nostart to a new function and use it there as well as in c_parser_omp_structured_block, c_parser_omp_{parallel,task} and c_parser_omp_sections_scope. It is very ugly to allow there declarations though, that means code behaves very differently between -fopenmp and -fno-openmp - in the former case the declared var would go out of scope immediately, in the latter would be around until closing }.
