yes, I do define properties when I check whether a subdirectory is available.
(And another user already alerted me to the fact that there seems to be a
problem if properties are set and passed to a new ant task at the same time -
which sounds like a good guess what's going on.)
Basically the macro checks

<available file="@{subdir}" type="dir" property="DirAvailable_@{subdir}"/>
<if><isset property="DirAvailable_@{subdir}"/>
   <ant dir="@{subdir}"/>

(etc., with some variations on the theme)

Well, I need quite a number of properties in my subtargets, unfortunately.
Would it possibly help if I did the directory testing in a separate ant target,
i.e. have the macro simply invoke a wrapper target that contains the current
macro code?

I guess it's worth a try.

I'll add some feedback if I find a workaround (which should give a good idea
what's going wrong).
