Shouldn't that be:

(*file)->pipe = <something>;

?

And the previous line should be:

(*file)->flags = flags;

(I submitted a patch for that one about 2 months ago).

It is the same bug :-)  I've just noted it as such.

Oh right :) (To most people, it just looks like the same bug as with
the flags line right above it.)

That's a placeholder for an decision not made (I believe we apr_pcalloc,
so it isn't a huge issue between = 0 or omitting it entirely.)

However, if we really were strict, we should call apr_file_info_get()
on the new file entity and set the pipe value based on the file type, no?

Definitely should be changed, even though it works fine now.
apr_os_file_put() assumes that it is a pipe, so it should be

  (*file)->pipe = 0;

or the code can simply be omitted since the structure is cleared.

if no Win32 committer speaks up/commits soon, I'll do it myself,
albeit with no test-compile

Thanks for persisting!!!!!
