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.
