8774: xine and xvmc won't work with --as-needed linker flag
 
When the --as-needed linker flag is given to xine, xine won't detect nvidia's xvmc, due to linker errors:

Accoriding to gentoo dev, Nvidia needs to fix it.

This is from config.log:

Re: 8774: xine and xvmc won't work with --as-needed linker flag
 
Either xine or Nvidia with 97.42 fixed this one as well. It also seems that xxmc with vld extensions are supported. I don't think this was the case with older driver. Need to test whether cpu usage is even lower now. :)
