Cross compilation failed

[He, Li]

Hi all. I want to make a Win32 port of GnuPG 2.0.10 from my sid with 
the help of mingw32.
$ dpkg -l "mingw32*"

I downloaded the following libraries for building GnuPG:
libgcrypt-1.4.4.tar.bz2
w32pth-2.0.2.tar.bz2
libgpg-error-1.7.tar.bz2
zlib-1.2.3.tar.gz
gettext-0.17.tar.gz
libiconv-1.12.tar.gz
readline-5.0-1-bin.zip
readline-5.0-1-lib.zip
libassuan-1.0.5
libksba-1.0.5.tar.bz2
libassuan-1.0.5.tar.bz2

When cross compiling libassuan, I got the following warnings:
configure: WARNING:
***
*** Data structure for sending ancillary data missing.
*** Descriptor passing won't work.
***
***
*** No implementation of fopencookie or funopen available.
*** The assuan_get_data_fp feature won't work.
***
But it succeeded in creating the library itself.

However when it comes to linking GnuPG, something went wrong:

I think there might be something wrong with my compilation of 
libassuan. But I am not sure what caused it. Could anybody tell me how 
to fix it?

Thank you a lot!
