Because of really huge amount of modifications here I've probably missed some minor stuff. I doubt if it's still compatible with gcc - some changes should be reapplied.
* windmill won't give wood
* hover text for heroes
* good background for the town hall screen in Stronghold
* fixed typo in hall.txt
* support for ZSoft-style PCX files in /Data (using SDL_image)
* minor improvements
* fixed problems with horde buildings (won't block original dwellings)
* giving primary skill when hero get level (but there is still no dialog)
* if an upgraded creature is available it'll be shown as the first in a recruitment window
* creature levels not messed in Fortress
* war machines are added to the hero's inventory, not to the garrison
* support for H3-style PCX graphics in Data/ (not tested)
* started doing support for ZSoft PCX graphics in Data/
* VCMI won't crash when is unable to initialize audio system
* fixed displaying wrong town defs
* minor fixes and improvements
* CDefEssential is now useful
* initGameState shouldn't overwrite starting armies
* loading more graphics (small creature icons, large hero portraits)
* functions for getting current valueof morale/luck (unfinished)
* added in CLodHandler function that returns CDefEssential with images from desired .def
* copySurface works correctly (I hope)
