Hello, I am having problems to build wolf-cpuminer on ubuntu 16.04,14.04 using mingw32. I compile it easily for linux, but i would like to compile it for windows. I am having  this problem after: sudo make and this is my configure command : sudo ./configure --host=i586-mingw32msvc

cc1: error: invalid option argument ?-Ofast?
cc1: error: unrecognized command line option "-flto"
cc1: error: unrecognized command line option "-fuse-linker-plugin"
 
and when I go to Makefile and delete these lines, i am having other errors. I am not sure, i am on the right place for asking this question, but I hope  somebody may have a clue what to do.

Thanks in advance !
