I don't need and I prefer static libraries only.

I used

--disable-dev-random

because otherwise (please correct me if I'm wrong) I need /dev/random without that option
(Windows XP and/or Vista). Is it correct?  Can I use /dev/random on Windows platform as well?
Or is  --disable-dev-random needed on Windows?
As you know I'm a GnuTls beginner. So please be patient.. :-)

Just to tell you the whole story, the libgpgcrypt was configured using

./configure --disable-shared --disable-rpath

But I don't think libgpg-error is involved in the reported issue.

I re-tried to compile gnutls and after the error message I made " touch 
lib/libgnutls-26.def" . Then I got the following error message

libtool: link: ranlib .libs/libgnutls-openssl.a
libtool: link: rm -fr .libs/libgnutls-openssl.lax
libtool: link: ( cd ".libs" && rm -f "libgnutls-openssl.la" && cp -p 
"../libgnutls-openssl.la" "libgnutls-openssl.la" )

I made "touch libextra/libgnutls-openssl-26.def". Then the same for 
libgnutls-extra-26.def, after another  "touch" I got

This time "touch" can't help :-).

Any other suggestion?

Nevertheless during compilation I got the followin warnings

The same warning is present for other files as well. Do you need a full 
list?

I was unable to find a new daily snapshot. May be it isn't available 
yet. I'm going to try as soon as the new snapshot is available.
