I've read this - but how did you actually *used* this setting.
What are you doing on your side to trigger the UDD option?

I admit I'm in doubt with all my Makefile knowledge.  Something is
really wrong.  Please have a short look at my short test Makefile:


#!/usr/bin/make -f

export GENCONTROLOPTS = "--udd"

export GENCONTROL_OPTS = "--udd"

testopts:
        echo ${GENCONTROLOPTS}
        if [ "$$GENCONTROLOPTS" != "" ] ; then \
            echo "GENCONTROLOPTS = ${GENCONTROLOPTS} ( $(GENCONTROLOPTS) )" ; \
        fi
        echo "Now test the underscore variable"
        echo ${GENCONTROL_OPTS}
        if [ "$$GENCONTROL_OPTS" != "" ] ; then \
            echo "GENCONTROL_OPTS = ${GENCONTROL_OPTS} ( $(GENCONTROL_OPTS) )" ; \
        fi


The result is

$ make testopts
echo "--udd"
--udd
if [ "$GENCONTROLOPTS" != "" ] ; then \
    echo "GENCONTROLOPTS = "--udd" ( "--udd" )" ; \
fi
GENCONTROLOPTS = --udd ( --udd )
echo "Now test the underscore variable"
Now test the underscore variable
echo 

if [ "$GENCONTROL_OPTS" != "" ] ; then \
    echo "GENCONTROL_OPTS =  (  )" ; \
fi


I know that we are using several variables in Makefiles containing
underscores and thus I have no clue what's happening here.  So it seems
the variable GENCONTROL_OPTS simply made it into the environment.  BTW
I also have done

    export GENCONTROL_OPTS="--udd"

in my bash environment which also did not helped. :-(

Checked and confirm that it works now.

Well, also apt cache is a moving target.  So if we do not talk about
reproducible test conditions and just want to debug the libodil0-dev
issue in a defined time frame, the debug task can be helpful.


In summary: I'm fine with a 0.7.0 release to unstable if there is a
documented way to turn on the UDD option.  (I'm obviously to stupid and
always need to trigger it manually. :-((((( )

Thanks again for your work on it

     Andreas.
