-Notes:

-
-Also, make sure that DLLFNAME_POSTFIX and (PRIVATEBUILD or SPECIALBUILD)
-are defined when compiling the resource file. DLLFNAME_POSTFIX contains
-the trailing letters that come after the version number. PRIVATEBUILD
-and/or SPECIALBUILD store information describing the type of change made
