I confirm that, and thanks for this fix which should make life a lot
easier for our Windows Visual Studio users.

I am allergic to letting bugs slide (especially if they involve the
build system) so could you explain the issue further?
On Linux the <top-level-build-tree>/drivers/<driver>.rc files are
configured by cmake (see the logic in
cmake/modules/drivers-finish.cmake). Those files describe which
devices have been enabled for each device driver. The test-drv-info
application generates exactly the same information from the driver
plugin that has been built, and there is a cmake custom target
(test_${SOURCE_ROOT_NAME}_dyndriver, see drivers/CMakeLists.txt) for
each driver that checks the two sets of information are identical as a
test that the driver plugin is OK. As far as I know, these
driver-related *.rc files all should occur in the drivers subdirectory
even on Windows. Do these files have anything to do with your
troubles above or is it something entirely unrelated?
If the troubles are due to some weird Windows nameclash with the .rc
suffix on the driver-related *.rc files, the motivation for that
choice of suffix is lost in the mists of time, and we could certainly
change that suffix to something else that is much more distinctive
(such as .driver_info).
