Huh? I thought the reason these functions exist is that otherwise you'd
have no portable way of getting a standard i/o handle that was an
apr_os_file_t. Which is a HANDLE on Windows, not an int, and
stdin/out/err aren't 0, 1 and 2, unlike Unix.

Yes, and the third "problem" is that APR on Windows doesn't use C file
functions, nor POSIX ones, it uses Win32 functions -- thank the gods --
and that's why apr_os_file_t exists.
