If they are just warnings, then there is no problem.  Those "warnings" 
are really just informative messages...it has been suggested that we 
silence them, but I dunno if the changes are "accepted" enough to 
justify silencing those messages.  It's been about four months; I 
(arbitrarily) set six months as my target age before I'd submit a patch 
to binutils-patches to silence them.

Again, are you SURE it's not working?  auto-import warnings are actually 
an indication that things are going well...

*PLEASE* post the ACTUAL output from your "failing" link command.

None of the above.  See my earlier message to this list "Re: dll vs 
static importing on cygwin".

My mistake.  As of 5.2-7, those references to ncurses_dll.h are out of 
date.  I should correct the documentation.

Sorry it was confusing.  If you have the following files, then you did 
it right:

/usr/bin/cygncurses6.dll
/usr/bin/cygncurses5.dll
/usr/lib/libncurses.dll.a
