In this context I believe that the $(MAKE) calls in debian/rules are 
implemented in a strange way...

You know, we call MAKE twice; once to build the static libraries and 
then again to build the shared libraries and the frontends. To build 
the static libraries we call MAKE from the top source directory. Then 
we backup the static libraries after compilation. Afterwards, to build 
the shared libraries and the frontends, we go down into each of the 
libraries' directories and call 'make clean && make' (roughly) there.

Is this still necessary, given that we do not manipulate Makefile.pic 
anymore, or could we simply run 'make clean && make' again from the 
top source directory instead? If it is possible, we should do this for 
the sake of clarity.

Another thing that I don't understand is, how it builds the ffmpeg 
frontend (which it obviously does) if MAKE is only run inside the 
subdirectories but not in the top directory...


Yet another issue in the context of debian/rules: As long as we don't 
run configure with --disable-optimizations, the {C,CXX,LD}FLAGS 
environment variables that are set by dpkg-buildpackage are simply 
ignored and overridden with dubious optimization flags in the range 
between -O3 and -O5. I consider this unacceptable and believe, all 
sources shuold be compiled with the same standard policy-conform set 
of flags that is CFLAGS="-Wall -g -O2".


Cheers,
Fabian
