You might want to use automake+autoconf+libtool, instead of just 
autoconf+libtool.

You don't need to do this.

Don't use dlltool.  It's old and crotchety.  Use gcc -shared (or 
libtool).  For examples, see the dllhelpers 
here:http://www.neuro.gatech.edu/users/cwilson/cygutils/dll-stuff/index.html

And make sure you're using a new(er) libtool/autoconf, like 
autoconf-devel-2.59 and libtool-devel-1.5.
