#pragma langlvl (C only)
In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, #pragma langlvl determines whether the source code conforms to a specific language standard, or subset or superset of a standard.
IBM Open XL C/C++ for AIX 17.1.4 does not support #pragma langlvl. You are recommended to use the -std Clang option instead.
