--- Comment #10 from Sveinar Søpler cybermax@dexter.no --- The reason i asked was because i have found some instability when compiling with gcc-mingw-w64-10.2 and using flags like -mavx "or higher" (eg -march=native)
As long as the CFLAGS is near or the same as CROSSCFLAGS i would say it should be no problems with what you post :)
Not sure what would have changed with this from gcc-9.3 -> gcc-10.2, or if it is just some particular code and randomness that happened, but i have had issues when using -march=native with earlier wine versions that would randomly crash when playing WoW for instance.
I have had no problems so far today (but not tested long) with battle.net and WoW using staging-6.0-rc1.
