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.

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.)

It makes little sense to enable the variant without the main format.

This avoids duplicating the full DEPEND_CMD line only to change some

Setting this value using ?= caused some trouble if it was already

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

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.
