if you are using Dev-C++, you can change the dll filename in Project->Project Options->Build Options->Override output filename
the Template source code will build a playable HPB_bot.dll file (non-metamod version), but it won't support waypoints.
edit:
I've also made HPB bot 3.0 source code (full non-metamod version with waypoint support) buildable with MinGW/Dev-C++, so if you need it:
