[patch] MinGW build

Hi,

the attached patch fixes a linker error and disables the "random" test
under MinGW because there's fork().
The patch does not include the Windows CryptoAPI patch proposed in
   
http://permalink.gmane.org/gmane.comp.encryption.gpg.libgcrypt.devel/1366
because it was rejected by Werner Koch and the CryptoAPI seems to be
unavailable on some Windows editions:
    http://www.gnunet.org/mantis/view.php?id=1028

Apply the patch with
    patch -p 0 < libgcrypt-mingw.diff
and rebuild ./configure using
    autoconf -f -i

A prebuilt DLL is available from gnunet.org:
    http://www.gnunet.org/download/win32/libgcrypt-1.2.2.zip


Best regards,

Nils Durner
