I assumed that anyone wanting to respond would do so to the mailing list they got it through if appropriate; for instance, I had a followup on just debian-devel. > * Josh Triplett wrote on Wed, Apr 09, 2008 at 12:34:18PM CEST: >> Libtool knows how to handle libraries for umpteen different systems, >> including many ancient systems that have terrible shared library >> support.
