So you build all of glib as one big dll and not 3 separate ones - glib, 
gthread, gobject and gmodule? I guess that make sense.

Yeah I could do that - but would make the automake stuff very different 
from the main glib. How much are you looking to be able to feed this 
work back into the main glib? Also how cross platform does it need to 
be? Will this code need to compile on Linux or others?
I have a fix for gmodule that allows it to work, I just made it the same 
as gobject (also a separate DLL)  where GOBJECT_VAR is used for the 
import/export of dll functions based on other defines.  I added a 
#define section to gmodule.h much the same as the one in 
gobject/gparamspecs.h
which seems to work, you can then still use G_MODULE_EXPORT and 
G_MODULE_IMPORT in the plugin dll's that use it.
Will make sure the tests all pass tomorrow, libtool still causes a few 
issues when using mingw.
