[issue45220] Windows builds sometimes fail on Azure and GitHub Action: fatal error RC1116: RC terminating after preprocessor errors

Steve, instead of manually defining RT_MANIFEST, try including "winresrc.h" in the resource definition files. This SDK header includes "winuser.rh" (note the ".rh" extension), which, among other things, includes the following RC_INVOKED definitions from "winuser.h":

    #ifdef RC_INVOKED
    #define RT_MANIFEST                        24
    #define CREATEPROCESS_MANIFEST_RESOURCE_ID  1
    #define ISOLATIONAWARE_MANIFEST_RESOURCE_ID 2
    #define ISOLATIONAWARE_NOSTATICIMPORT_MANIFEST_RESOURCE_ID 3
    #define ISOLATIONPOLICY_MANIFEST_RESOURCE_ID 4
    #define ISOLATIONPOLICY_BROWSER_MANIFEST_RESOURCE_ID 5
    #define MINIMUM_RESERVED_MANIFEST_RESOURCE_ID 1   /* inclusive */
    #define MAXIMUM_RESERVED_MANIFEST_RESOURCE_ID 16  /* inclusive */
