That seems reasonable to me, but I do think *something* needs to change, 
the current behaviour is very confusing.  Libtool seems to just drop 
options on the ground, and unless you're watching the libtool output 
it's not immediately obvious until something breaks.

Perhaps there should at least be a patch to make libtool warn when it's 
ignoring options?
