Over the years, IBM has offered a variety of compiler products to perform the compilation of C and C++ programs on AIX. These C and C++ compilers have evolved over time and can be tracked by their different version numbers. The C and C++ compilers introduced new compiler features to take advantage of the functionality included in new releases of the AIX operating system.
This appendix gives you background information on versions of C and C++ compilers prior to C for AIX version 6.0 and VisualAge C++ for AIX Version 6.0, by providing the following sections.
