The level of synchronicity on this issue is starting to get me
suspicious.

Taking up Corinna's point from yesterday, none of the unexported
functions from <stdio.h> are SUSv3 functions, they're all BSD-isms.
Then again, they are all just wrappers that call other (already
exported) functions, so size isn't much of an issue and you don't get
any extra funcionality.

A more important point I've tripped over is that cygwin doesn't seem
to provide implementations of the flockfile etc. functions used by
stdio to lock the FILE objects, and so the current version is not
thread-safe. Is that true? says I in some pain, having just gone
through cygserver replacing all <iostream.h> calls with <stdio.h>
calls to avoid a thread-safety problem in the C++ library :-(

Just for the record, the list of unexported functions from <stdio.h>
is currently:

    getc_unlocked
    getchar_unlocked
    putc_unlocked
    putchar_unlocked
    setbuffer
    setlinebuf
