-    fix map() command on 32-bit platforms; regressed in 5.2.0
-    
-    LuaJIT FFI was using opendir() (etc.) variants with 32-bit inodes
-    but the C parts was using them as 64-bit inode variants.
-    Consequently the `struct dirent` layout didn't match and we were getting
-    filenames shifted by eight bytes.
-    
-    Now the whole dir-listing lua function is written in C.
