The 64 bit cl.exe version 16.00.30319.01 crashes with an internal
compiler error on the current check (and thus deduces it isn't
supported, even if the actual usage in libavuil/x86/cpu.c works
fine), but by assigning the value from the intrinsic to a variable,
or returning it, it works fine.
This error is fixed in cl.exe version 16.00.40219.01.

Some msvcrt versions (the static 64 bit libc in MSVC 10) have
a log2 function, but there is no declaration for it in the headers.
Therefore, the normal configure check might find it, but it can fail
during build or at runtime, depending on whether implicit function
declarations are an error or not.
Therefore simply ignore this function on this platform.

Rather than modify the mplayer filter sources, just disable
vf_mp if inline assembly is not available.

It is included for the open/read/write/close functions. On
MSVC, where this header does not exist, the same functions
are provided by io.h, which is already included.
On windows, these functions are provided by io.h. Make sure
io.h is included if it exists, regardless of the setmode
function.

Make internal small_strptime() function public, and use it in place of
strptime().
This allows to avoid a dependency on strptime() on systems which do not
support it.
In particular, fix trac ticket #992.
This disables the following warnings:
C4100: unreferenced formal parameter
(1035 occurrances)
C4214: nonstandard extension used : bit field types other than int
(609 occurances)
C4996: 'avpriv_snprintf': This function or variable may be unsafe.
Consider using _snprintf_s instead. To disable deprecation,
use _CRT_SECURE_NO_WARNINGS. See online help for details.

yasm generates a warning instead of an error when "CPU amdnop" is not supported, so the check always succeeds.
HAVE_CPUNOP as true when the available yasm version doesn't support amdnop doesn't make sense.
Check http://fate.ffmpeg.org/log.cgi?time=20120901143315&log=compile&slot=x86_64-archlinux-gcc-oldyasm to see the amount of warnings it generates.

This enables replacing the -l and -L flags used to specify the
just-built libraries when linking the tools and shared libs with
non-standard syntaxes. System library flags are already handled
by the filtering mechanism in configure.

Some tools use different command line syntax for specifying output
when compiling and linking. To accomodate these, separate variables
must be used. No currently supported compilers/linkers are affected
by the change.

There is no point in having the user disable any fastdiv macros.
Besides the condition implementation was broken and only disabled
the C implementation, but no platform specific assembly versions.
For some compilers ISA older than mips32r2 is set as default.
Because of them assembler flag "-mips32r2" needs to be added
for CPUs that support mips32r2 ISA in part of configure script
where ISA capabilities are checked.
"-mhard-float" assembler flag is also added for CPUs that have FPU.

There used to be one test for Altivec intrinsics support and a
separate test to determine which of two possible syntaxes to use
for vector literals. Since 2008, we only support the more common
of these so the split test no longer makes sense.
This combines the tests into one and also changes the hard error on
failure to a warning. The test can reasonably fail if no --cpu flag
is provided (or is provided with an unknown CPU) and the compiler
default target does not support Altivec. Aborting in this case is
probably over-reacting.
