As I said in a previous message, you should try with the developement 
branch of the autotools, as provided by the cygwin distribution (located in 
/usr/autotool/devel/bin : modify your PATH accordingly). Currently, this is

automake 1.7.5
autoconf 2.57
libtool 1.5

This development branch does not use impgen anymore when building DLLs on 
win32 but instead relies on the -shared option of the gcc/g++ compiler 
(which is much faster !!!). Also, make sure that '
-no-undefined -Wl,--export-all-symbols' is among the LDFLAGS is the library 
Makefile.am, except if a .def file is provided with the library (I don't 
think so).

As an example, see the Makefile_build.am_fragment file in the build_shared 
directory of the latest stable gtkmm tarball.

Also, you should first try to build a static version of the library 
(./configure --disable-shared) and fix win32-related bugs before any 
attempt of making a DLL !!!
