Ugh, that's unfortunate. :-(

Thanks for your suggestions Aleksey.  However, it appears that neither 
of these are doing quite what I had hoped for (although the glob 
solution is sufficient at this point).  In particular, the result of the 
glob and mtime and never recomputed.  So, if I have "omake -P" running, 
it won't notice any new or removed files from the directory.  This isn't 
really a big problem, but it would be nice to have so that I wouldn't 
ever have to restart omake :-D.  I also tried adding a regular 
dependency on $(TEST_DIR), but this didn't seem to work (but seems like 
the most likely candidate to have these semantics, since directories are 
just files).  Is there a way to achieve this?

Thanks again,
