I'm sorry, I wasn't clear. I didn't fix anything; I just submitted a
bug report as Vladimir asked me to.

If the appropriate maintainers fix the "os versus target-os" bug, it
will not necessarily remove the need to manually link ws2_32, pthread,
and other libraries. That's a different bug. Perhaps you should submit
a bug report about that.
