20 patches done, 65 more to go! 
I will be starting on a set of these next. 

current git compiles ok on updated Slackware, no more weird asm error {but I still workaround my libx11  location! And opencv static compile still need some diet..} 

I installed glibc 2.33/gcc 11.2 from Slackware 15.0 - but I plan to test on gcc 5.5 from time  to time..
