How does mod_ssl.so fail to load exactly?

I don't quite understand why is "entry point" considered wrong? It's not
inappropriate for shared library to have an initialization code and how
would it be handled without entry point? Or does AIX run-time linker
handle it in some magical way? If so, how?

The real reason for passing -G through -Wl is that rule in question is
expected to work even with gcc, not only cc. So if -bnoentry is actually
required, then it's more appropriate to complement -Wl with -bnoentry,
not take -G out. Or it might be more appropriate to move -G to
./Configure, to $shared_ldflags [and -shared to corresponding gcc target]...

AIX doesn't stop to amaze/puzzple... I don't have regular access to AIX,
but I can't recall such messages... A.
