Win32 binding

["Antonio L�pez" <alm@gtd.es.REMOVE>]

I am using the Win32 binding that comes with the Gnat compiler in order to
interface with the API of a Dll.

When searching for an use example of "type    ULONG_Array is array (Natural
range <>) of aliased ULONG;", I found only one in win32-rpcndr.ads.
However instead of declare an array, it declares the elements alone, calling
for "storage unit bounday".

I have searched for "storage unit bounday", but I don0t understant the
concept and/or the problem. Can some enlight me, please?

Cheers,
Antonio

--  @@ with GNAT the type ULONG_Array must be aligned at a storage

--  instead.
