GCC is sometimes able to optimise constant calls to these functions,
incorrectly indicating that they exist. Unoptimised calls will then
fail to link.

These are often, contrary to standards, implemented only as macros
or compiler-builtin functions without an actual symbol definition.

Some SoCs have a small amount of on-chip SRAM which may be used
for frequently used code or data. When enabled, this option
will allow FFmpeg to use such facilities where supported.

This makes us link directly to getaddrinfo if it is available, making

Originally committed as revision 21409 to svn://svn.ffmpeg.org/ffmpeg/trunk
It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.
To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h)
The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

Silly BSD systems need this despite POSIX requiring nothing of the
kind. Any system with sys/socket.h should also have sys/types.h,
so this is unlikely to break anything, and we already do this in
another place.

This in particular ensures that -DPIC is set appropriately for YASM, which avoids
linking failures on x86_64 for compilers that have PIE enabled by default
(e.g. hardened Gentoo).
It also makes the macho64 special-case hack adding -DPIC to YASMFLAGS obsolete.
Originally committed as revision 20497 to svn://svn.ffmpeg.org/ffmpeg/trunk
and -DPIC makes little sense without -fPIC or similar - if -fPIC is
enabled by default, libavutil/internal.h defines PICi anyway.
Originally committed as revision 20486 to svn://svn.ffmpeg.org/ffmpeg/trunk
This covers the previous case of x86_64 and shared, but also
works with --enable-pic.
For 32 bit x86 it currently makes no difference since x86inc.asm
ignores -DPIC for non-x86_64.

At least for cross-compilation with Gentoo gcc 4.4.2 it fixes the build errors
due to GPREL 22 being insufficient for the .bss size of > 4 MB without it.
Why these errors do not appear with static builds is unclear, it is not due
to PIC (shared builds with PIC disabled show the same issue).

Recent versions of gcc generate movw/movt pairs, and the linkers fail
to handle the associated relocations properly. Those responsible at
Codesourcery have refused to consider fixing this. Blame them for
making shared libraries slower than they need to be.

ebx_available if both "b" constraint and exb clobber code compile.
This is to fix compilation with Mac OSX 10.5.8's gcc 4.0.1 in 64
bit mode (-m64) which only fails for ebx/rbx clobbers but not
"b" constraints - this is probably a compiler bug.
