Look at current Makefile.in - it explicitly lists each and every variable
passed down. I just accomodate its current style.

Exactly. That's why there are ugly constructs like:

        "`echo 'LANGUAGES=$(LANGUAGES)' | sed -e s/.*=$$/XFOO=/`" \

Which passes down LANGUAGES iff it is set. I will use it for my future
patches too, unless somebody has got a nicer one.
