When I'm trying to create win32 wine prefix by setting WINEARCH=win32 prefix
virtual drive is not populated.

I'm using following sequence:
$ rm -Rf ~/.winetest
$ WINEPREFIX=/home/pasha/.winetest WINEARCH=win32 wineboot -u 
wine: created the configuration directory '/home/pasha/.winetest'
wine: cannot find L"C:\windows\system32\wineboot.exe"
err:process:start_wineboot failed to start wineboot, err 2
wine: cannot find L"C:\windows\system32\wineboot.exe"

$ find .winetest/
.winetest/
.winetest/drive_c
.winetest/drive_c/windows
.winetest/drive_c/windows/system32
.winetest/dosdevices
.winetest/dosdevices/z:
.winetest/dosdevices/c:
.winetest/system.reg

$ cat .winetest/system.reg
