HI Ticker,
I think new Garmin maps have a lot more bits set, but GPXSee doesn't even read
the basic 8 bits,
so I can leave the code as is for now.

Hi Gerd
An interpretation of the comment is that POIGlobalFlags data is 16
bits, and, if bit 9 is set, the next byte is the number of extra word
of POI information immediately following. The data then continues with
2 bytes unknown, POITypeIndex Position/Size/ItemSize...
As mkgmap always writes z
Hi Ticker,
I don't understand. The number of bytes doesn't change, the
patch just places more information in the flags field instead of
ignoring them.
I am not aware of any code in mkgmap that reads or fills those bits,yet.

Hi Gerd
Reading it more carefully, probably the basic flag set is 16 bits, with
0x0100 indicating more bytes to read/write

Hi Gerd
Although the comment might have inaccuracies and be ambiguous, it
contains useful information about how the extra flags for POI might be
represented, which could be different from just reading 4 bytes.
One way of interpret it is if (first byte & 0x80), then read/write
extra bytes; the 3
