You were asking someone else to run the autotools for you because you
could not be bothered to install autoconf and autoconf2.13 packages from
Debian testing on your computer? Wow.

Well, that remark would apply to any piece of software, especially
a compiler. But if upstream's bootstrap script was well thought and
accepts your version of the tools, there is no reason it should not

As an author and/or autotools build system maintainer for at least
10 different projects (none of them requiring a specific version of the
autotools) I can tell you that this is absolutely not necessary, even
for a project as complex as ffmpeg. (by the way, I would be happy if
ffmpeg used that scheme because it makes cross-compiling and feature
detection a lot easier, but I am in no way trying to advocate it over
any other build system as far as ffmpeg is concerned)
