The test gfortran.dg/namelist_97.f90 dos not clean the file test.dat

[dhumieres.dominique@free.fr]

Hi all,

While investigating pr95538, I see a file test.dat that is not cleaned.
I traced this to the test gfortran.dg/namelist_97.f90.
I was wondering why the statement

   close (unit=10, status='delete')

did not delete the file, until I realized that it was never executed due 
to the runtime error.

This leftover may cause failure of tests using

   open(unit=99, file='test.dat', status='new')

(see pr95546).

Any idea how to clean the file? Meanwhile it could better to rename the 
file, say 'namelist_97.dat'.

Cheers,

Dominque
