hi Daniel,
here is my proposed patch to allow, at configure, time the production
of shared library with versioned symbols. i used it to build curl
7.14.1-1 debian package now in experimental.
i'd be very glad to see it applied to your source tree. feel free to
modify any part of it but please let me know the final tag name in
lib/libcurl.vers.in in order to match it in the next upload to debian
unstable.
cheers
domenico
