However it's not trivial to reproduce. I had to run the built binaries on a
virtualization server with OpenVZ kernel 2.6.32.

The problem manifests in most (by not all) service entries missing in a freshly
created ~/.wine/system.reg, and RpcSs is one of the missing services.

Reverting the offending commit on top of wine-6.4, replacing open/read/close by
_lopen/_lread/_lclose, and changing O_RDONLY to OF_READ, fixes the bug in
wine-6.4 as well.
