[MPlayer-dev-eng] Altivec+GCC fix

[Arpi]

Hi,

applied!

> here's a new patch that makes it possible to use
> altivec-accelerated playback under Linux.
> 
> * configure
>   Check for altivec.h and set HAVE_ALTIVEC_H
>   This is required for the new libmpeg2 files and for 
>   the updated ffmpeg code
>   make sure ARCH_POWERPC gets set
>   (I choosed this instead of mpeg2_internal)
> 
> * libmpcodecs/vd_libmpeg2.c
>   Make sure that altivec gets enabled in libmpeg2
> 
> * libmpeg2/Makefile
>   Make sure the correct flags are passed to CC
>   Altivec files should only be compiled when altivec is enabled.
> 
> * libmpeg2/idct.c
>   Only use Altivec if enabled with configure.
> 
> * libmpeg2/motion_comp.c
>   Only use Altivec if enabled with configure.
> 
> * libmpeg2/idct_altivec.c
>   Updated to version 1.19 from sourceforge
>   This version includes the gcc bugfix
>   The new file also ditches the old assembly version
>   and it must be built with correct altivec-flags
> 
> * libmpeg2/motion_comp_altivec.c
>   Updated to version 1.12 from sourceforge
>   The old version crashed my gcc-3.2.2 (after allocating 1 Gig memory)
>   because of unfriendly altivec code, the new file is better.
>   The new file ditches the old assembly version
>   and it must be built with correct altivec-flags
> 
> / magnus
