[mkgmap-dev] Patch: use all 4 bytes of POIGlobalFlags in LBL Header

Sat Feb 12 12:36:34 GMT 2022

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 zero/unknown bytes not being part of this flag set.
