[x264-devel] Problem with SSSE3 instructions

This will cause problems, because Visual Studio will currently create
builds that crash because it does not support the stack alignment
method used to support the SSE2 deblocking routines.  This is because
there is no C standard method of aligning the stack, so a GCC-specific
method is used.  Patches are welcome for an MSVC version.

This is normal.  x264 uses autoloading assembly, so it picks the
correct functions for your CPU on runtime.

This means your assembler is too old and doesn't support modern instructions.
