Ok, now I guessed that I could use avx2=1 rather than sse4=1, and took me 18 minutes.
Code
set path=c:\mingw64-w64\bin
make -j5 TARGET=ume NOWERROR=1 PTR64=1 USE_NETWORK=1 avx2=1
Someone knows where I can find a list with these parameters that I can use, or at less the best compiling string for my processor? I tried to find it, but I don't had sucess
