[mkgmap-dev] Split gmapsupp.img

As far a I know, mkgmap is able to produce unlimited size gmapsupp 
files, but SD cards and internal device memories have a limit of 4 GB in 
a single file. To overcome that limit, recent versions of Garmin City 
Navigator maps are split into several gmapsupp that work as a single one 
in devices which include them. Would it be possible to add an option to 
mkgmap, so that it automatically splits gmapsupp when you process a map 
that is larger than 4 GB?
