48 * Define what support for C++ streams is available.
49 * If U_IOSTREAM_SOURCE is set to 199711, then <iostream> is available
50 * (1997711 is the date the ISO/IEC C++ FDIS was published), and then
51 * one should qualify streams using the std namespace in ICU header
53 * If U_IOSTREAM_SOURCE is set to 198506, then <iostream.h> is
54 * available instead (198506 is the date when Stroustrup published
55 * "An Extensible I/O Facility for C++" at the summer USENIX conference).
56 * If U_IOSTREAM_SOURCE is 0, then C++ streams are not available and
57 * support for them will be silently suppressed in ICU.
