 * (1997711 is the date the ISO/IEC C++ FDIS was published), and then
 * one should qualify streams using the std namespace in ICU header
 * files.
 *     If U_IOSTREAM_SOURCE is set to 198506, then <iostream.h> is
 * available instead (198506 is the date when Stroustrup published
 * "An Extensible I/O Facility for C++" at the summer USENIX conference).
 *     If U_IOSTREAM_SOURCE is 0, then C++ streams are not available and
 * support for them will be silently suppressed in ICU.
