This commit refactors the internal gfc_omp_namelist structure within GCC’s Fortran front-end, specifically moving the udm field into a new union, u3. This adjustment resolves a potential data clash that could occur when OpenMP mappers and iterators were used simultaneously. The change ensures that these two features can coexist without internal conflicts, improving the robustness of OpenMP support in Fortran.
