Hi Charles,

Thank you for the feedback!

Great!

I postponed that part on purpose.  The ever-increasing number of
configure switches is frightening.  OTOH, choice is good in this case,
IMVHO.  Maybe we can get away with one switch for all of them.  Like
this:

  --disable-ltdl-loaders=LOADER[,...]

But there actually is another point I forgot to mention:
(3a) if both dlopen and LoadLibrary are used on cygwin, the former
     _must_ be tried first by ltdl.  I believe you mentioned that this
     is not the case ATM (haven't checked yet).

I would really like to fix them in order, i.e., fix (4) last.

Cheers,
Ralf
