--- Comment #10 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The error for the test in comment 8 is now (from 4.8 up to trunk 6.0)

pr31560_1.f90:6:29:

   integer, dimension(dataset%maxsiz) :: nobs
                             1
Error: Symbol 'dataset' at (1) has no IMPLICIT type

Is there any hope to emit an error of the kind "used before it is defined"? or
should this PR closed as FIXED?
