Use -fp:fast as a substitute for -ffast-math.
Increase warning level from -W0 to -W1 (the default setting).
Disable -GS (stack cookies) on MSVS. It's disabled by default on ICL.

Fixes out-of-tree MSVS builds on Cygwin.

`cl -showIncludes` creates absolute Windows paths for some files, attempt
to convert those to Unix paths.

Use relative paths for dependencies located in or below the working directory
in order to mimic the behavior of gcc and to make the paths more readable.

Make the dependency generation script a bit more robust in general.

Also remove some non-POSIX syntax and improve robustness.

As a bonus the script now runs about 2-3 times faster.

`git rev-list --count` could be used to simplify things even further,
but that functionality was added in git 1.7.2 so keep `wc -l` for now
to maintain compatibility with older git versions.

Those are false positives, but it doesn't hurt to get rid of them.

Visual Studio 2015 has a proper snprintf implementation.

/usr/bin/link from coreutils may be located before the MSVS linker in $PATH
which causes linking to fail due to using the wrong binary.

It's undefined behavior to use the same va_list twice.

This most likely didn't cause any issues in practice since the string would
have to be larger than 4 KiB to trigger the fallback path.

Use workaround for ICL as it doesn't define va_copy even for C99.

GCC doesn't have an "-arch" switch, but works when that entire line is removed.

MSA is the MIPS SIMD Architecture.

Add X264_CPU_MSA define.
Update configure to detect MIPS platform and set flags.
CPU-specific gcc options are expected through --extra-cflags.

Sample command line for mips32r5:
    ./configure --host=mipsel-linux-gnu --cross-prefix=<TOOLCHAIN>/mips-mti-linux-gnu-
    --extra-cflags="-EL -mips32r5 -msched-weight -mload-store-pairs"

This is attempt to improve VBV at start of video with a lot of threads which
delay feedback for predictors.

This should improve MBTree and VBV when a lot of forced frame types are used.

For NV21 input.

Eliminates an extra copy when encoding Android camera preview images.

Checkasm test by Janne Grunau.
ARM assembly with improvements from Janne Grunau.

Enables the use of nasm as an alternative to yasm.

Note that nasm cannot assemble x264 with PIC enabled since it currently doesn't
support [symbol-$$] addressing which is used extensively by x264's PIC code.
This includes all 64-bit Windows and 64-bit OS X builds, even non-shared.

For the above reason nasm is currently intentionally not auto-detected, instead
the assembler must be explicitly specified using "AS=nasm ./configure".

Also drop -O2 from ASFLAGS since it's simply ignored anyway.

struc and endstruc attempts to revert to the previous section state set by
the SECTION macro.

Use the primitive [SECTION] directive instead of the SECTION macro for the
.note.GNU-stack section to prevent it from being emitted again during endstruc.

The .text section is already 16-byte aligned by default on all supported
platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.

The bug was fixed in 1.3.0, so only perform the workaround in earlier versions.

Just for consistency, doesn't affect behavior.

PIC is always enabled when compiling for Windows so gcc complains when using
-fPIC since it doesn't do anything.

The StereoMode element is only valid with DocTypeVersion 3 or higher.
