[gdal-dev] GDAL/OGR 3.4.1 not reading S57 correctly

[Momtchil Momtchev]

     I get exactly the same layers in /ogrinfo/ as I do with your 
program both with GDAL 3.3.2 and GDAL 3.4.1 on all of your S57 files. 
/s57/1B5X02NE.000/ has 13 layers.

     Here is the program I used: https://pastebin.com/z99xeQ92
