To follow up on my own posting, it seems like the libltdl 
documentation should include a summary of the capabilities it 
claims/expects to portably support, and what it is expected to be used 
for. Libltdl is not really a portable dlsym() wrapper since dlsym() 
supports many non-portable behaviors.  In order to support its 
portability objective, libltdl should support the lowest (acceptable) 
common denominator functionality, and this functionality should be 
documented.
