Many compilers need special flags to compile *.h files as regular
source code, if they will do so at all.  Rather than hoping all
compilers will have such a flag and adding mappings for it, create
wrapper .c files for test building single headers.

This allows using the regular rule for compiling C files without the
need for special flags, and it also provides proper dependency tracking
for these objects.

This option specifies the name of live stream to subscribe.

When streaming live streams using the Akamai, Edgecast or Limelight CDN,
players cannot simply connect to the live stream. Instead, they have to
subscribe to it, by sending an FC Subscribe call to the server.

Some compilers do not support the Q/R modifiers used to access
the low/high parts of a 64-bit register pair.  Check for this
and disable all uses of it when not supported.

It appears that something goes wrong in old nasm versions when the
%+ operator is used in the last argument of a macro invocation and
this argument is tested with %ifdef within the macro.  This patch
rearranges the macro arguments such that the %+ operator is never
used in the last argument.

nasm does not support 'CPU foonop' directives.  This adds a configure
test for the directive and uses it only if supported.

For some reason, nasm requires this.  No harm done to yasm.

yasm tolerates mismatch between movd/movq and source register size,
adjusting the instruction according to the register.  nasm is more

Ensures that the next frame decoded after seeking will be decoded as a
keyframe.

Fixes mpc8 timestamps.

This simplifies adding extra flags for individual programs
and also allows more than one object file per program.

The check is bogus since the nuv frameheader is already skipped
and the (decompressed) RTjpeg header is checked.

In the GNU assembler, a relational expression, bizarrely, has the

The clang integrated assembler does not support pre-UAL syntax,
while gcc requires pre-UAL syntax for ARM code.  A patch[1] for
clang to support the old syntax as well has been ignored since
January.

This patch chooses the syntax appropriate for each compiler,
allowing both to build the code.  Notably, this change allows
building for iphone with the latest Apple Xcode update.
