This is because you forgot to select the "relocatable" scenario for
win32ada. E.g. when using gprbuild:

   grpbuild -P... -XWIN32ADA_BUILD=relocatable

There is a static build of win32ada which is the default scenario.

 E.g.
----- test.gpr >>>>>>>>>>>
with "win32Ada.gpr";
library project Test is
   for Library_Name use "test";
   for Library_Kind use "dynamic";
   for Library_Dir  use "c:/temp";
   for Library_Interface use ("test"); 
   for Library_Standalone use "standard";
end Test;
----- test.gpr <<<<<<<<<<<

---- test.adb >>>>>>>>>>>
with GNAT.Sockets;  use GNAT.Sockets;
with Win32;         use Win32;
with Win32.WinBase; use Win32.WinBase;
with Win32.WinNT;   use Win32.WinNT;

function Test return String is
   Self : HANDLE;
begin
   Self := GetCurrentProcess; -- Windows API call
   return Host_Name; -- GNAT.Sockets call
end Test;
---- test.adb <<<<<<<<<<<

gprbuild -d -PC:\Temp\Z\test.gpr -XWIN32ADA_BUILD=relocatable
gcc -c test.adb
gprlib.exe test.lexch
gnatbind -n -o b__test.adb -Ltest -a C:\Temp\Z\test.ali
gcc.exe -c -x ada -gnatA -gnatws b__test.adb -o b__test.o ...
gcc.exe -shared -shared-libgcc -o C:\temp\libtest.dll ... C:\Temp\Z\test.o
...
