Why do you think it should be libio?

It's not standard, and not included in the cygwin runtime.

I don't know what you mean. libio is part of libstdc++ (GNU C++ runtime
library), and is definitely been compiled under cygwin.

If your code uses/needs it, you have the following choices:
  - modify newlib's vfscanf and export it from the Cygwin DLL. I'm
    sure patches will be welcome so that it can be included in the
    next release. See newlib/libc/stdio/vfscanf.
  - write your own. You can use the newlib version, with minor 
    modifications.

If you contribute an implementation, the Cygwin folks might include it.
