/**************************************
macros to define byte pattern for a GUID.
Example: DEFINE_GUID(GUID_XXX, a, b, c, ...);
Each dll/exe must initialize the GUIDs once. This is done in one of
two ways. If you are not using precompiled headers for the file(s)which
initializes the GUIDs, define INITGUID before including compobj.h. This
is how OLE builds the initialized versions of the GUIDs which are included
in ole2.lib. The GUIDs in ole2.lib are all defined in the same text
segment GUID_TEXT.
The alternative (which some versions of the compiler don't handle properly;
they wind up with the initialized GUIDs in a data, not a text segment),
is to use a precompiled version of compobj.h and then include initguid.h
after compobj.h followed by one or more of the guid defintion files.
