---  This unit is the root of a set aimed at offering Ada bindings to a subset
---  of the Intel(r) Streaming SIMD Extensions with GNAT.  It exposes vector
---  _component_ types together with general comments on the binding contents.
-
---  The purpose is to allow access from Ada to the SSE facilities defined in
---  the Intel(r) compiler manuals, in particular in the Intrinsics Reference
---  of the C++ Compiler User's Guide, available from http://www.intel.com.
-
---  As of today, essentially one unit is offered: GNAT.SSE.Vector__Types,
---  which exposes Ada types corresponding to the reference types (__m128 and
---  the like) over which GCC builtins will operate.
-
---  The exposed Ada types are private. Object initializations or value
---  observations may be performed with unchecked conversions or address
---  overlays, for example:

+--  Assuming actual hardware support is available, this capability is
