gtkmm don't link properly on windows

[Yose Widjaja <wyos cse unsw EDU AU>]

Hi,

I have dev-c++ and mingw32 gcc on my windows box. Just yesterday night, I 
installed gtkmm as according to this instruction:

http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ape.html

However, when I tried to compile a simple c++ file using ustring, it spat 
out this kind of messages:

C:\DOCUME~1\dante\LOCALS~1\Temp/cc4eaaaa.o(.text+0x73):main.c: undefined 
reference to `Glib::ustring::ustring()'
C:\DOCUME~1\dante\LOCALS~1\Temp/cc4eaaaa.o(.text+0x88):main.c: undefined 
reference to `Glib::ustring::ustring()'
C:\DOCUME~1\dante\LOCALS~1\Temp/cc4eaaaa.o(.text+0x9d):main.c: undefined 
reference to `Glib::ustring::ustring()'

The linker and include flags, I obtained from pkg-config --cflags --libs 
gtkmm-2.4.

the c file is just something like this:

using Glib::ustring;
using std::string;
using std::cin;
using std::cout;
////////////////////////////////////////////////////////////////////////////////////////
int main(){

   ustring a, b, c, d, e, f;

   cin >> a;
   cin >> b;
   cin >> c;
   cin >> d;
   cin >> e;
   cin >> f;

   cout << a << b << c << d << e << f;
   return 0;
}

Sorry for the long question. Does anybody have any idea why?

Cheers
