--- Comment #8 from Alexandre Julliard julliard@winehq.org --- The build system can be fixed so that make install works, but note that the filesystem that hosts the WINEPREFIX requires symlink support because of the DOS devices handling. That's probably the failure you got when running from the build tree, and that's not something that can be fixed on the Wine side.
