Ah, but libtool is supposed to decide internally whether it is safe to link
libraries in on the system it is invoked on.  So the dependencies should be
in the Makefile.am -- They just won't be used on all platforms.

Does 1.0f not work this way?  I'm working on patching library dependencies
into libtool and I'm pretty sure they will provide functionality in this
manner.  (Should appear in 1.1 or 1.2 release, after Gordon looks over my
patches and tests/incorporates them.)

Would that then be acceptable?
