Chris,

The attached patch eliminates warnings such as the following:

In file included from /usr/include/g++-3/set:31,
                 from ../main.cc:145:
/usr/include/g++-3/stl_tree.h: In function `int __black_count(_Rb_tree_node_base *, _Rb_tree_node_base *)':
/usr/include/g++-3/stl_tree.h:1258: warning: can't inline call to `int __black_count(_Rb_tree_node_base *, _Rb_tree_node_base *)'
/usr/include/g++-3/stl_tree.h:1266: warning: called from here

Would you be willing to accept this patch into the Cygwin gcc source tree?

Thanks,
