1. Stop shouting (caps letters).
2. Make sure your cygwin distribution is working as expected. You should 
try, for example to build a C++ library that has no external 
dependencies,  the latest libsigc++-1.2 for example. In the libsigc++-1.2.5, do

export PATH=/usr/autotools/devel/bin:$PATH      % Using the development 
branch of the autotools
gcc -v                                          % Making sure we use cygwin gcc
libtoolize --force
aclocal -I scripts
automake -a
autoconf
./configure --disable-static
make

If the libsigc++ DLL (along with its .dll.a import library) is not created 
in sigc++/.libs, you really have a problem with your cygwin distribution. 
If it works, try to build a more complex library, gtkmm for example !

3. Try to remove all .la file in the binary distribution you downloaded 
from http://web.sfc.keio.ac.jp/~s01397ms/cygwin. Libtool might sometimes 
get lost if these .la were created for a different directory structure.

4. Did you run configure with --disable-static ?

5. Did you try to compile a small gnome application with the binaries from 
http://web.sfc.keio.ac.jp/~s01397ms/cygwin, just to test your installation.

6. Did you contact Masahiro Sakai ?

7. You should realize that you're first who tries to compile 
libgnomecanvasmm on cygwin (with Sagar Shah who also posted on the 
mailinglist). This is not like building helloworld.c ! So please, be 
patient. I'm sure there is a solution.
