Applications that use the new run-time library features will not run on RVUs prior to H06.08
unless the new run-time library SPRs are applied. Applications that use the new compiler features
cannot be recompiled on RVUs prior to H06.08 unless the new C compiler SPRs and standard
header SPR are applied.
For descriptions of the new c99 standard features currently supported by the C compiler and

C H06.09 and Later Fallback
Starting with the H06.09 RVU , the C++ Version 3 runtime library (ZCPP3DLL) is upgraded to
the latest release of the Dinkumware C++ runtime library in order to support the ISO/IEC IS
14882 language specification and to upgrade the exception handling mechanism in the H-series
C++ Version Neutral DLL (ZCPPDLL) for improved performance.
In the event of a fallback, applications compiled with the upgraded headers must be recompiled;
otherwise, they will not execute on the earlier RVU.
