I'm trying to use sockets in ada with gnat 3.10
I used glade as an example for calling to windows socket calls
however I get problems with linking
This is a part of the code showing the problem

--
with interfaces.c;
pragma Linker_Options ("-lwsock32");


procedure test_sock is
   package c renames interfaces.c;

   package net is
      function C_Listen (S, Backlog : C.int) return C.int;

   private
      pragma Import (C, C_Listen, "listen");
   end net;

  s,backlog,result : C.int;
begin
  result := net.C_Listen(s,backlog);
end test_sock;


-- this program compiles correctly but does not link it gives the following
error:

gnatlink test_sock.ali -lwsock32

./test_sock.o: In function `ada_test_sock':
//C/USR/ada/l11/test_sock.adb:17: undefined reference to `listen'

the linker can find the libwsock32.a because when i change the name it
cannot find it
