But I think for now it's enough if you only change the 64-bit, isn't it? Thomas

With regards, Daniel

Building at -O2, adds 33% to the build time, over -O2. IOW a build that takes 45 minutes at -O0, takes 60 minutes at -O2. Turning off debug symbols drops it further, down to 38 minutes. IOW, a "-O2 -g" build is 58% slower than a "-O0" build on msys in the gitlab CI windows shared runners. Signed-off-by: Daniel P.
