missed them in r19293. Re-enable version check on w32api.h if the
vfwcap input device has been selected.

It is possible that the compiler requires flags set by the --cpu
option, so we should not attempt to run it before those flags have
been added.

We do not issue similar warnings for other architectures, and we
generally assume users know what they want.

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.

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 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.

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.

--enable-indev, --enable-outdev rather than --enable-demuxer,
--enable-muxer as before, same for disabling them.
