Hello,

  I've built Freewitch 1.8.7 and 1.10.3 successfully from sources on Centos-7. however, it fails on centos-8 while building VPX. Before I dig into it, anyone noticed this also?

An example for one of the errors:
vpx_scale/generic/vpx_scale.c:286:26: error: ‘vp8_horizontal_line_2_1_scale’ undeclared (first use in this function); did you mean ‘horiz_line_scale’?
       horiz_line_scale = vp8_horizontal_line_2_1_scale;
                          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                          horiz_line_scale

I can  find the declarations inside the WIN tree, but I am not using Windows :-)

                              Thanks, __Yehavi:
