There is a cmake define for the version with underscore: https://github.com/llvm/llvm-project/blob/main/openmp/runtime/src/CMakeLists.txt#L171
I'm wondering whether the gnu C++ headers for **solaris** probably test for the variable without underscores. Can you possibly grep in the C++ headers on your solaris system for the variable?
