Code review comment for lp://qastaging/~epics-core/epics-base/rsrvbindiface

I'm not quite sure what this means, but on my Windows & Cygwin box:

It's likely that Cygwin would see those same routes, and it uses the osi/os/default implementation (how would I test that?). We might want to add similar code to the osi/WIN32/osdNetIntf.c but I don't really understand what that's doing at line 134, so I'm not going to suggest we make any changes to that right now.
