[Lazarus] Using Lazarus to build a (Linux) shared library, with a form

I'm struggling here. I can build a trivial (empty) .so using Lazarus 
1.1+2.6.0, the only necessary manual operation being to tell the project 
options to remove the (Windows-specific?) -Wr option. I can load the 
result at runtime, although I've not so far put significant code into it.

As soon as use Lazarus to add a form to the project, it no longer loads. 
In order to find out what's going wrong I've had to use dlerror(), i.e. 
bypassing the dynlibs library since it doesn't have a function e.g. 
GetLoadErrorStr(). This shows me that the low-level dlopen() is 
complaining "undefined symbol: WSRegisterCustomImageList".

What do I have to manually add to the project to get this working?
