FFmpeg configure does not warn about unknown parameters, it errors out, just try "./configure --enable-foo". The parameters above are not unknown, they are useful for debugging but not for users, this is why they are not listed in configure --help (that was what you both denied and requested, no?). The options you use in your configure line are to some degree useless, to some degree they hurt performance for no gain and some (as --enable-zlib) do not work the way you (apparently) think they work: They simply have no effect. Since the configure line is often needed to debug issues it is very useful to remove all unneeded options, especially those that may produce issues in the future because they never had the meaning you think they have.
