It's a bug in 1.5.10 that these files can be created. That will be fixed
in the next version.
In the meantime, build the below source with
gcc ntdel.c -o ntdel -lntdll
Let's say, the directory in which you created "nul" is C:\your\dir, then
you should get rid of that file with
ntdel c:/your/dir/nul
