optimized out by gcc when the headers lied about the function existing,
rendering the test useless in that situation.
This new test throws a warning in mingw-w64, but that should not be a problem.

The auto-vectoriser in gcc is enabled by default at -O3 since version
4.3. However, it provides no speed benefit, but does produce incorrect
code on many targets. Disabling it for gcc should give more reliable
builds.
If the adventurous want it back, they can edit the makefile themselves.

Altivec, NEON, and SSE require more alignment than standard malloc()
guarantees, whereas MMX does not. Update checks to reflect this.

If ff_neterrno() is checked instead of errno, that's probably what should be
used in the return value.
As a sideeffect, this gives better compatibility with Windows (CE), where
network errors aren't visible in errno.)

On Windows CE, the Winsock library name is ws2, not ws2_32.

This allows use of the add_*flags functions in the compiler detection
section.

This fixes compilation on WinCE, which does not support _lseeki64.

This can be used to map gcc-type flags to equivalents with other
compilers.

This avoids duplicating the full DEPEND_CMD line only to change some
flags.

Setting this value using ?= caused some trouble if it was already
defined in the environment.

Some of the values set here are modified by the main makefiles
and should not be reset when config.mak is included again.

rather than prepend it.
This way there is the guarantee that the included headers are those in
the FFmpeg sources, rather than pre-installed headers referenced by
the user CPPFLAGS.

Some compilers do not use the typical -c -o foo.o style.
This allows compiler-specific equivalents to be set by the
configure script.

The VAAPI/VDPAU variants of foo require almost all of the code of foo.
Thus it makes little sense to enable just the accelerated variant.
This allows refactoring some object dependencies in the Makefiles.

current code doesn't handle them properly, and they are a dubious construction
at best.
