cant compile with mingw about freeserf HOT 2 CLOSED

hmm threading solved using lib SDL2, following fixes are required:
freeserf-master\buildgw\src\CMakeFiles\profiler.dir\linklibs.rsp
add -lSDL2 switch at end for correct linking,

then edit game.cc following WAY, include section:
#ifndef MINGW32
#include
//namespace std_boost = std;
#else
//fix for mingw
#include <SDL2/SDL.h>
#include <SDL2/SDL_thread.h>
#include <SDL2/SDL_mutex.h>
#endif
....
....
void
Game::update_flags() {

#ifndef MINGW32
Log::Verbose["game"] << "thread #" << std::this_thread::get_id() << " is locking mutex for Game::update_flags";
mutex.lock();
Log::Verbose["game"] << "thread #" << std::this_thread::get_id() << " has locked mutex for Game::update_flags";
#else
//mingw threading support
SDL_mutex* mut=SDL_CreateMutex();
SDL_LockMutex(mut);
#endif
...
...
#ifndef MINGW32
Log::Verbose["game"] << "thread #" << std::this_thread::get_id() << " is unlocking mutex for Game::update_flags";
mutex.unlock();
#else
//mingw threading support
SDL_UnlockMutex(mut);
SDL_DestroyMutex(mut);
#endif
}
