+/* dx_guids.c
+ *
+ * Emits DirectX COM GUID storage in lieu of linking dxguid.lib.
+ *
+ * The Windows 7.x Platform SDK (bundled with MSVC 2010 and earlier)
+ * does not ship dxguid.lib. Rather than require the legacy June 2010
+ * DirectX SDK just to pick up a handful of IID_* / CLSID_* constants,
+ * we define them ourselves in this single translation unit.
+ *
+ * Including <initguid.h> before any DX header causes DEFINE_GUID() to
+ * expand to actual storage rather than extern references. Every other
+ * TU in the program continues to see the default extern declarations
+ * and resolves the GUIDs to the storage defined here at link time.
+ *
+ * IMPORTANT: no other TU in the program may include <initguid.h>
+ * before DirectX headers, or the linker will report duplicate symbols
+ * for IID_* / CLSID_* constants.
+ *
+ * This file is for the non-griffin build. The griffin build gets the
+ * same behavior by including <initguid.h> at the top of griffin.c.
+ *
+ * The guard below disables this TU on:
+ *   * non-Windows platforms
+ *   * Xbox (its own SDKs provide GUID storage)
+ *   * UWP / WinRT (the modern Windows SDK ships dxguid.lib)
+ *   * griffin builds (griffin.c does the job there)
