Alas, it is necessory for all libraries that your DLL depends on to
also be built as DLLs.

Since Windows DLLs do not allow undefined symbols, a requirement to
build a DLL using libtool is to include the -no-undefined option,
otherwise a static library will be built.

Libtool 1.5 is much better at enforcing these rules than former
versions of libtool.
