Right, that's a neat approach that I like.

Hm, I'm not entirely happy with that: I want to show the libssh2 version
number when used by an app. I'm not so sure I want that app to show or even
care about the openssl/libz situation there, even if I can think that in other
situations the app or other users of libssh2 might care. Alas, I'd like to get
the "1.0.0" separately from "openssl/gnutls/libz"...
So what do you think about this:
const char *libssh2_version(int req_version_num, const char **extra);
So if 'extra' isn't NULL, it gets set to a pointer with "openssl/libz" style
info and the function returns "1.0.1_CVS" ?
It still makes it possible to do things like:
if (!libssh2_version(LIBSSH2_VERSION_NUM, NULL)) {
fprintf (stderr, "Runtime libssh2 version too old!\n");
exit(1);
}
