Update to 0.3, add WITHOUT_OPENSSL knob. I have created a patch for configure
to add a few new flags. If it causes any trouble, I will remove it.
* --disable-openssl (autocheck: enable by default)
* Add CC and CFLAGS in configure for anyone can edit it.
I have submitted this patch to the author.
I believe that it can be done in Jamfile instead configure, I will have to
learn more abot Jamfile later for what features and what it can do. If anyone
know any better way or so, let me know.
