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.
Originally committed as revision 20107 to svn://svn.ffmpeg.org/ffmpeg/trunk
The test using clobber incorrectly indicates ebx to be available with the
default compilers on OpenBSD 4.5 and Haiku.

Apparently some versions of armcc do not identify as RVCT. This
changes the test to a string used by all versions.

Remove gcc-specific hacks and allow filling relevant information for non-gcc
compilers in configure.

As a sideeffect this moves more interesting variables to the top of config.mak.

if the "shared" var has not been explicitely enabled, rather than if
it has been explicitly disabled.
This way is not necessary to explicitly disable shared libraries in
order to have a pc file usable with only static libraries.

libx264 recently started mangling the name of x264_encoder_open() to
prevent version mismatches, breaking our test. Checking for another
function instead makes it work again.

This makes comma-separated patters to --disable-decoder and friends
work correctly with POSIX-compliant shells.
Originally committed as revision 19688 to svn://svn.ffmpeg.org/ffmpeg/trunk
Using this flag enables position-independent code even when not strictly
required. It is impossible to use --disable-pic to forcibly disable PIC
when other properties mandate it.
Originally committed as revision 19672 to svn://svn.ffmpeg.org/ffmpeg/trunk
Recognise AVR32 processor names as well as the generic "ap" and "uc"
family names as values for --cpu. Also define two subtypes, avr32_ap
and avr32_uc.

We do the same for libschroedinger and already use pkg-config to generate
the CFLAGS for libdirac anyway, so there is no new dependency.
Thanks to Kovensky for reporting breakage on IRC.

When running behind ccache, the output from -MMD is corrupted unless
we also use the -MF and -MT flags.
Since ccache is difficult to detect and gcc 2.x doesn't support the
-MF and -MT flags, we always use the old dependency generation method
when gcc 2.x is detected.

-mdynamic-no-pic is required for it, but it was only
added to CFLAGS and the check only used ASFLAGS.

The argument to these options is now a comma-separated list of shell
patterns, e.g. --disable-decoder='indeo*,rv*'
Originally committed as revision 19604 to svn://svn.ffmpeg.org/ffmpeg/trunk
The name can now be a standard shell pattern. For example,
--disable-encoder=* disables all encoders.
Originally committed as revision 19603 to svn://svn.ffmpeg.org/ffmpeg/trunk
This requires a gcc version with -march=native or -mcpu=native support,
which is somewhat random for non-x86.
Originally committed as revision 19602 to svn://svn.ffmpeg.org/ffmpeg/trunk
Instead, #include config.h at the top of common.h so that av_always_inline
does not get doubly defined.
Originally committed as revision 19553 to svn://svn.ffmpeg.org/ffmpeg/trunk
This avoids a ton of redefinition warnings.
