yes, would be better. I'll see how to do this. Current implementation first reads
the style, prints the warnings, and finally shows what is contained in the info file.
I can change it so that check-styles starts with a line containing the current style name.

ok

You can do this if you specify style-file=<path_to_styles>/mystyle --check-styles

Hm, mkgmap uses only the lowest 8 bits and thus treats 0x3d00 like 0x00, and it is not able to write polygon types with values between 0x7f and 0xffff.
With lines the invalid range is 0x3f to 0xffff. 

Does anybody know how these types would be encoded in the img format that we write? Or does it require NT format?
