Hi Chris (& list),

Thank you for making your modifications to wxLua available.

I was able to get the sources with Subversion; unfortunately, my
problems persist. It appears that gcc 3.4.4 (MinGW) is unable to
compile wxLua. This was my problem all along, I guess.

In wxLuaSplitTree.cpp I needed to add the lines
#ifdef __MINGW32__
#undef UNREFERENCED_PARAMETER
#endif
to get it to compile. Otherwise there is an error compiling
 void wxRemotelyScrolledTreeCtrl::PrepareDC(wxDC& dc)
because wxDC is not assignable, and UNREFERENCED_PARAMETER is defined
by default to perform an assignment. I suspect that MSVC is permitting
the assignment because the result is unused as well. Dunno.

I also had to add a
#if wxUSE_ON_FATAL_EXCEPTION
around
static int LUACALL builtin_wxHandleFatalExceptions(lua_State *L)
and
    { LuaGlobal,      "wxHandleFatalExceptions", builtin_wxHandleFatalExceptions, 0, 1 },
since gcc doesn't do structured exception handling.

The final stumbling block was the inability of gcc to compile
wxLuaWrap.cpp at all. I get an Internal Compiler Error in
 WXLUAOBJECT *GetObjectList(size_t &count)
as gcc is unable to deal with the static assignment to objectList[]. I
tried moving the assignment, and removing individual elements in a
binary search for the root of the problem, but got nowhere.

It would be nice to be able to use wxLua with MinGW. Oh, well.
