No, I am not.  None of my (very small) original source contributions are 
autotool'ed <hangs head in shame>.  My interest is in making it easier 
to get a working, autotool/libtool system for building DLL's on cygwin 
"transparently" -- e.g. just like so's on unix.  Then, I can more easily 
port stuff to cygwin; I'm not *really* that concerned about originating 
software on cygwin (although that may be important to other people).

Since robert collin's hacked version of libtool which meets this goal 
requires:

auto-import changes in binutils
   --> completed (a few pending problems, but mostly there)
up-to-date autoconf
   --> 2.52 package for cygwin was released a few weeks ago
automake-1.4i or later
   --> so I've been tracking recent automake development. Hopefully, 
when automake-1.5 is released (and verified to work acceptably on 
cygwin), an official cygwin package will be released soon thereafter.

Therefore I've been meddling (read: I've been a major PITA :-) in the 

developers' mailing lists for those projects recently.
