Thanks for mentioning this.  I asked on the bug-dejagnu list back then,
and have an answer now:
http://thread.gmane.org/gmane.comp.sysutils.dejagnu.bugs/345/focus=348

I think we should change Automake semantics here and provide a relative
srcdir only.  That would mean, the first patch I suggested in
http://thread.gmane.org/gmane.comp.sysutils.automake.bugs/5230/focus=5464

Stefano, would you like to rewrite your testsuite addition for this?

Thanks,
Ralf
