Why is the configure not adding them on it's own ?

$ uname -a
Darwin MACSFT001 7.4.0 Darwin Kernel Version 7.4.0: Wed May 12 16:58:24
PDT 2004; root:xnu/xnu-517.7.7.obj~7/RELEASE_PPC  Power Macintosh powerpc

I do have openssl. In fact, as I already said, just adding -lssl to the
compilation line solve the problem: But why is it not added automatically ?

| Regarding second set, you just have to use a typecast.

Hum, which one? The failure is in a big mysql++ macro that lookis pretty
complex. Is there a patch somewhere for this ?

Thanks for your answer.
