    Fortran/OpenMP: Fix var-list expr parsing with array/dt
    
    gcc/fortran/ChangeLog:
    
            * openmp.c (gfc_match_omp_variable_list): Gobble whitespace before
            checking whether a '%' or parenthesis-open follows as next character.
    
    gcc/testsuite/ChangeLog:
    
            * gfortran.dg/gomp/map-5.f90: New test.
    
    (cherry picked from commit e4aefface2a0e34d84b85844b11652eb28f2cf0c)
