Subject: Tech note on FastCGI libs for NT


I ran into a bug in the FastCGI library code I did for NT that I
wanted to pass along.  This bug is in beta libraries (yes, it's in
both beta 1 and beta 2).

The bug is in the file os_win32.c.  The FILE_FLAG_OVERLAPPED flag is
passed to the "CreateNamedPipe" function and this is wrong.  Delete
this flag and rebuild your libraries.  This flag is leftover from some
experiments I was doing with overlapped I/O on NT and should have been

This flag can cause the call to ConnectNamedPipe to return a false
"connected" indication when used without overlapped I/O.  The problem
is very subtle but will drive you a bit mad trying to figure out what
is actually going on.

A fix has been checked into the main repository here at Open Market
and it will be in the next release (no, I don't have a date for this

Hope this info is useful.
