win64 dll shared library

I recently revisited cross compiling from linux to windows.

ubuntu 10.04 (mingw32 that comes in the repos) works just fine

$mkdir win32output
$./configure --host=i586-mingw32msvc --prefix=`pwd`/win32output
--enable-shared
$make
$make install
$ls win32output/bin/
bsqldb.exe  bsqlodbc.exe  datacopy.exe  defncopy.exe  freebcp.exe 
libct-4.dll  libsybdb-5.dll  libtdsodbc-0.dll  osql  tdspool.exe  tsql.exe

note that the dlls are created.

Now on ubuntu 10.04 (prebuilt mingw-w64 8/17/2010 from
mingw-w64.sourceforge.net)

$mkdir win64
$export PATH=$PATH:/home/thomas/mingw-w64-bin_i686-linux_20100817/bin
$./configure --host=x86_64-w64-mingw32 --prefix=`pwd`/win64
--enable-shared
$make 
$make install
$ls win64/bin
bsqldb.exe  bsqlodbc.exe  datacopy.exe  defncopy.exe  freebcp.exe  osql 
tdspool.exe  tsql.exe
$ls win64/lib
libct.a  libct.la  libsybdb.a  libsybdb.la  libtdsodbc.a  libtdsodbc.la

No dlls are created. Is shared library / dll creation supported for win64?
