C H06.08 and Later Fallback

Beginning in the H06.08 RVU, the TNS/E C compiler (T8164ABH for c89, T0549AAE

for CCOMP), C Standard Headers (T8645H02), and the C run-time libraries

(T8432H02 for the C Run-Time Library, T1269H02 for CRE) provide a subset of new

features from the new ISO/IEC 9899:1999 standard.

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 run-time library, see the C/C++ Programmer’s Guide.
