Hi John,

Thank you for this idea. I have compiled treeentry_gtk.c file as C++ as 
described in
http://msdn.microsoft.com/en-us/library/032xwy55.aspx
and errors gone

Unfortunately this change could not be applied because wxWidgets uses 
automatically generated makefiles and project files, and it looks like 
current build system (bakefile) not supports this option. Also this file 
probably will not be renamed to *.cpp just because troubles with current 
GTK+/Win32 API.

It looks like there is troubles with __cplusplus usage in GTK+/Win32 
headers.

Eventually I built wxGTK3/Win32 and minimal sample, but when I run this 
sample I have error message:
---------------------------
minimal.exe - Entry Point Not Found
---------------------------
The procedure entry point gdk_atom_intern could not be located in the 
dynamic link library libgtk-3-0.dll.
---------------------------
OK
---------------------------

But gdk_atom_intern is inside libgtk-3-0.dll file:

$ objdump -x libgtk-3-0.dll|grep gdk_atom_intern
        49d180      9  gdk_atom_intern
