/*
* We also ignore this warning in ./configure, but that's not always enough.
* The flags that are used during compilation by ./configure are determined by
* the compiler support it detects. This is usually GCC. This warning is only
* present in clang. So it would normally be fine to not use it with GCC. The
* problem is that clang is used to compile the JIT bitcode when postgres is
* compiled with -with-llvm. So in the end both clang and GCC are used to
* compile the project.
*
* So the flag is not provided on the command line, because ./configure notices
* that GCC doesn't support it. But this warning persists when compiling the
* bitcode. So that's why we ignore it here explicitly.
