Great, many thanks for your help. I could compile against openssl
headers w/ few changes in claws mail code, but I'm stuck on a linking
problem.

First, libeay32.dll from the gnuwin32's openssl package conflicts w/
the one shipped w/ kdesupport included in gpg4win. I could easily sort
out this, but NOT installing the one from openssl (it's still 0.9.7
whereas the one from kdesupport is 0.9.8). Waiting for an openssl 0.9.8 packag from gnuwin32.

But my main problem now is that libssl requires linking against
libgw32c.a (if I'm not wrong, at least it's defined in the .pc file),
and if I install the g32c package from gnuwin32 (including it as a
gpg4win module), linking will show a conflicts between symbols defined
in that gw32c lib and the mingw32 libc one.

I've noticed that libpng's .pc shows that it is linked against gw32c
too, but I wonder how applications built with gpg4win do work with
this, any idea?
