I hope (below) is what you are asking for.
This is a very interesting problem to me. Apache has two support libraries:
apr and apr-util. The problem is with apr-util. The libtool call for apr
appears to me to be "the same" and produces correct results. The only
significant difference I see if apr-util has -lexpat -liconv.
expat is a staticly linked library and it is the one that causes libgcc_s to be
needed due to setting up exception handling. apr needs libgcc_s "directly"
(one of the object files being linked needs it) where as apr-util does not need
it directly but only because of expat's needs.
