The --enable-shared is not supported by Octave currently. It shouldn't be
hard to add the shared support, but it's work and someone must do it. If
anyone is interested in the work, I can elaborate on what needs to be done
to build Octave as a dynamic library or DLL; DLLs are quite different from
what we typically call shared libraries on Unix.

You can still use --enable-dl and use dlopen/dlclose (which are buggy
under Cygwin b20.1 and fixed in dev snapshots since), but each loadable
.oct file will be *huge* because all symbols in DLLs must be resolved 
and you'll end up including the entire octinterp in each .oct file.

Please don't use --enable-shared.
