-v, -V

In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, the -v or -V option reports the progress of compilation by naming the programs being invoked and the options being specified to each program.

In IBM Open XL C/C++ for AIX 17.1.3, use the -v option instead. Its format and compilation steps are somewhat different from those of -v or -V in the old releases.
