There are Win32 bindings for that. If you have a compiler for Windows
you probably have them.

Even if some of API are not listed there it is usually quite easy to
call them manually using pragma Import. For example:

with Interfaces.C;
with Win32.WinDef; use Win32.WinDef;
with Win32.WinNT; use Win32.WinNT;

function LoadImage (Instance : HINSTANCE;  ...) return HANDLE;
pragma Import (StdCall, LoadImage, "LoadImageA");

Generally the same way as you would do it in C or Basic.
