[Bug libgomp/41737] New: [omp] missing error for undeclared variable in a parallel region with default(none)

[jv244 at cam dot ac dot uk]

In the attached code, the last parallel region is default(none), but doesn't
declare np.This should generate an error instead (at least it does with cray
and intel compilers).

simplified testcase, for 4.8:

INTEGER :: ip,np
!$omp parallel do default(none)
  DO ip=0,np
  ENDDO
!$omp end parallel do
END 

while it is OK for ip to have no explicit attribute, I believe the standard
requires one for np. Intel ifort gives:

est.f90(3): error #6752: Since the OpenMP* DEFAULT(NONE) clause applies, the
PRIVATE, SHARED, REDUCTION, FIRSTPRIVATE, or LASTPRIVATE attribute must be
explicitly specified for every variable.   [NP]
