Looks as if adding the pragma in the two .cpp files also seems to work:


     // Record flushed pages as claimed
+    PRAGMA_STRINGOP_OVERFLOW_IGNORED
     Atomic::add(&_claimed, flushed);


Not sure why it doesn't work when I put the pragma in `PlatformAdd::add_then_fetch` in `atomic_linux_riscv.hpp`.
