[Wien] Error in nlvdw

Perhaps it's just my system but the WIEN2k 19.1 nlvdw, which has been 
compiled with gfortran (gcc version 7.4.0 under Ubuntu 18.04.4 LTS), is 
behaving strangely.  It seems to get hung up trying to open 
$file.outputnlvdw in SCR_nlvdw/vdw.F.  In x_lapw, I see 
$file.outputnlvdw defined as unit 6.


It might be that use of unit 6 in the nlvdw package is problematic when 
compiled with gfortran similar to what we saw for SRC_symmetry:
