Compiling x265 for Win32 target (here in MSYS2/MinGW32) is not possible  
anymore.

Assembler code was still available for 8-bit depth core, at least. But:

Trying to compile AVX-512 instructions may have to be avoided in 32-bit  
architecture mode (because there is surely no 32-bit only CPU supporting  
this instruction set extension).
