# files needed explicitly.

# This works by building a list of all children (recursively) of the
-# test sources. For each child we check, wether a file with the same
+# test sources. For each child we check, whether a file with the same
# name but an $OBJSUFFIX extension exists as a build target. In that
# case, we add it to the list of needed objects (AND recursively scan
# that objects children).
