Final Frontier Trader

trying to compile fftraders on fc5 linux I got the following errors

units.h:244: error: extra qualification ‘MapObject::’ on member
‘IsLoaded’
units.h:356: error: extra qualification ‘Map::’ on member
‘GetAIUnitImageW’
units.h:357: error: extra qualification ‘Map::’ on member
‘GetAIUnitImageH’
make: *** [guiapply.o] Error 1

I removed the extra qualificationssa follows

[none@localhost fftrader]$ diff units.h units.h~
