resource_check_usage Unhandled usage flags 0x8

[Luis C. Busquets Pérez]

I do not from which exact version of wine, whenever I run Civilization
IV bryond the sword, losts of fixmes appear with the message

fixme:d3d:resource_check_usage Unhandled usage flags 0x8.

Since those fixmes did not appear before I wonder if this is a bug.

I do not understand how it is that the function resource_check_usage
uses a flag that before it wasn't, was it? Can anybody clarify the usage
of the flag 0x8 and if this is a bug?
