Right -- and they are used in ipc-daemon and libcygipc.  However, as 
usual, Microsoft did not follow the POSIX standard interface for IPC 
stuff.  They windows-ized everything.  We have to write wrappers around 
the low-level Win32 calls so that they look POSIX.  (Worse, it's not 
really a one-to-one mapping.  There's other weirdness).

Paul "reappeared" in early August, but he's dropped out of sight again. 
  He wrote on the mingw-dvpr mailing list on August, 4 2001:

"I would like to greet you after more or less sizable break. since the 
beginning of summer, I stayed in the other city, studying and being on 
vacation. I've got a short recess for reading backlog of email before 
leaving for another academic course.  I'm going to pursue that kind of 
activity - academic and job - also for the near future."

I think we need to consider Paul MIA.  Somebody's going to have to 
REALLY dig in to the autoimport code and lick this bug -- it ain't gonna 
be Paul.

Right.
