Ye, I suppose that we can solve that if and when that will happen.

@LevShisterov currently I'm thinking about the names for constants of different hull numeration. I have several ideas for it:

1. PMOVE_HULL_* because it is related to playermove code.
2. PLAYER_HULL_* because it is related to player_mins and player_maxs variables.
3. MOD_HULL_*/DLL_HULL_*/GAME_HULL_*/something else because sizes for these hulls are controlled by gamedll via GetHullBounds callback.

Also I'm using player_mins and player_maxs in SV_HullForBsp:https://github.com/dreamstalker/rehlds/blob/65c6ce593b5eabf13e92b03352e4b429d0d797b0/rehlds/engine/world.cpp#L198-L208 So, now it is not only for players and looks like we should prefer the 3rd option. What do you think?

And btw, where it should be located? If we put it in model.h too and, for example, ReGameDLL_CS will include it with util.h together for GetHullBounds, then there will an error about *_hull redefinition.

About hull enumeration.
Mod_LoadClipnodes makes the things crazy, it doesn't match player_mins/player_maxs. I mean that if you want to make enum for model.hulls all references to that field should be processed. And it is hard to determine exact namings for constants. Naming them HULL_1, HULL_2, etc doesn't makes a lot of sense. At least I wasn't able to figure out namings for these fast. Probably you have some suggestions.
In SV_GetPlayerHulls looks like MAX_MAP_HULLS should be used.
