// Author(s):     jlarmour

// Contributors:  

// Date:          2000-04-20

// Purpose:       Initialization of stdout stream for ISO C library

// Description:   We put all this in a separate file in the hope that if

//                no-one uses stdout, then it is not included in the image

// Usage:

// stdin/out/err are not available
