Now reproduced in trying to build 11.0-BETA4 -r303759. But there is no
11.0-BETA4 Version selection available yet. So use 11.0-BETA3 selection for
now.



The "variably modified '_ArrayTables' at file scope" messages refer to (various
.h files contributing):

#define MAX_VDEVICE_PER_VBUS 8
. . .
#ifndef MAX_ARRAY_PER_VBUS
#define MAX_ARRAY_PER_VBUS (MAX_VDEVICE_PER_VBUS*2) /* worst case */
#endif
. . .
#define ARRAY_VDEV_SIZE ((UINT)(ULONG_PTR)&((PVDevice)0)->u+sizeof(RaidArray))
. . .
typedef struct _VBus  {
. . .
#ifdef SUPPORT_ARRAY
        PVDevice pFreeArrayLink;
        BYTE    _ArrayTables[MAX_ARRAY_PER_VBUS * ARRAY_VDEV_SIZE];
#endif
. . .
} VBus;



ARRAY_VDEV_SIZE is what is being complained about for its use in typedef struct
_VBus at file scope.
