Not sure if I already mentioned it somewhere:
./aldor/aldor/test/Makefile.in
has
-Cargs="-Wconfig=$(aldorsrcdir)/aldor.conf
with _xtests.

If someone uses clang and/or e. g. -pie or other options via "./configure ..." suddenly one gets a
inherit = gcc
from aldor.conf, so a build might fail.

Sure, one could adapt "aldor.conf" before starting the build of aldor,
but maybe someone has a nicer idea.
