Yes, this worked, but without the --index option - I only began using
it recently, when the index branch was merged back to trunk. (it still
works without --index in recent versions)

OK, I now also tried to modify the command line, feeding mkgmap
individual tiles, plus the overview-map.img of each layer, too.
Now all layers are present in the gmapsupp.img, but I lost all layer
names, .TYP files and the search index.

Or should I include the *.mdx file? I think I'll try that tomorrow.
