Comment 5 for bug 804559

the patch submitted by Gennady <https://svn.boost.org/trac/boost/attachment/ticket/4524/ipc_sem.patch> has not been applied in the version of boost currently in the DC++ repo.

at a first glance at the file in question, this might affect Windows builds (Windows-specific stuff is within an elif-guard that comes after the if-guard changed by the patch).
