<pre>This one seems like an easy enough fix; the for loop in
COFF/Driver.cpp:parseModuleDefs just needs to set e2.{ordinal,noname,isPrivate}
in the forwarding case.
Steps to repro:
$ touch example.c
$ cl /nologo /c example.c
$ cat example.def
EXPORTS
Sleep=kernel32.Sleep @123 NONAME PRIVATE
$ link /nologo /subsystem:windows /dll /out:example.dll /implib:example.lib
example.obj /def:example.def
$ dumpbin /exports example.dll
<...>
ordinal hint RVA name
123 [NONAME] (forwarded to kernel32.Sleep)
<...>
$ dumpbin /exports example.lib
<...no exports...>
$ lld-link /nologo /subsystem:windows /dll /out:example.dll /implib:example.lib
example.obj /def:example.def
$ dumpbin /exports example.dll
<...>
ordinal hint RVA name
1 0 Sleep (forwarded to kernel32.Sleep)
<...>
$ dumpbin /exports example.lib
<...>
ordinal name
Sleep
