Hi,
i use the same gtk bundle on win 7 and everything works
(treeviews, menus, etc).
It was just more picky and exposed some little bugs I've done
mostly by abusing gtkentry private const char strings.
I also needed to force it to show icons in buttons
with a call in code to set the property as it did not want
to honour gtkrc. I use codeblocks as IDE and latest
Tdm-gcc as compiler (http://tdm-gcc.tdragon.net/download).
I also force glib to use libc's standard allocators
by calling this function at app start:

void my_mem_init(void)
{
        GMemVTable gMemVTable;

        gMemVTable.malloc      = malloc;
        gMemVTable.realloc     = realloc;
        gMemVTable.free        = free;
        gMemVTable.calloc      = NULL;
        gMemVTable.try_malloc  = NULL;
        gMemVTable.try_realloc = NULL;
        g_mem_set_vtable( &gMemVTable );
}

Hope this helps.

Ciao,
