Trying to get wx.dll working on Win32, too, I've found a lot of problems 
in building the DLLs of wxLua.

In particular, it looks like the different modules need somehow stuff 
which is in other modules to link so that I ended up to compile first 
all files and then link them all together in a single monolithic DLL 
library.

This is 99% because all modules use the same WXMAKINGDLL_WXLUA symbol 
while for various reasons they should use different ones for the 
different modules.

Since, in my personal experience, building as DLL can be a BIG pain (you 
have to be very careful about WXDLLIMPEXP symbols, inter-module 
dependencies and in general in the entire build system), I propose to 
make wxLua buildable as a set of modules when SHARED==0 and as a single 
monolithic DLL library when SHARED==1.

What do you think ?

Also, what about moving "luamodule" dir to wxLua\modules ? Can I commit 
that change ?

Thanks,
Francesco
