#ifndef HB_NO_DIAGNOSTIC_PRAGMAS
/* Rules:
* - We set all pragmas under GCC, even clang-specific ones. Clang
* still reads them.
* - If GCC understands a warning, we declare it as GCC. Otherwise, clang.
* - Within each category, keep sorted.
* - Warnings whose scope can be expanded in future compiler versions shall
* be declared as "warning". Otherwise, either ignored or error.
