Fine.  If you want to be strict about it, sure.  Point being that, just
like autotools, you also place a requirement on a specific
command-shell.  Does that work for you?

Sure, if you want.  That's also part of the gcc toolchain and a requirement.

Similar.  You are keeping dependencies on disk and relying on, most
likely, gcc -MM or similar  (see a problem below with that).

True.  You have a bash script that spits out variables with cat <<EOF.
PREFIX=$PREFIX.

Not true, the make system currently imposes the compiler
to be compatible with gcc's flags (-MM for example needs to spit
dependencies, etc. ) besides any assembler.

Even if I add a proper stdint.h to MSVC for example, there's no way that 
the current make system will actually work for it, as -MM does not spit 
dependencies under that compiler.

Any way you look at it, the ffmpeg system is very similar to autotools. 
  It is just simpler and customized to ffmpeg.  But fundamentally, it is 
identical.

A make system that I would call really different would be something like 
scons or bjam (that does not even use make at all) or something like 
rake (which uses meta-programming to define rules).

The *original* point of the thread was about .lib files without
versioning and how that prevents easily
installing/shipping/deploying/supporting ffmpeg and future versions.  So
far, you have not explained to me how the current approach is superior.

Parallel building works in ffmpeg (never said otherwise).
But out of source for multiple platforms simply does not work as
reliably as autotools.

I'll post the issues with out-of-source I see in a separate thread.
