This is a regression from the upgrade to clang 16.
with clang 14:
#include "..." search starts here:
#include <...> search starts here:
/usr/include/wasm32-wasi/c++/v1
/usr/lib/llvm-14/lib/clang/14.0.6/include
/usr/local/include
/usr/include/wasm32-wasi
/usr/include
End of search list.
with clang 16:
#include "..." search starts here:
#include <...> search starts here:
/usr/lib/llvm-16/lib/clang/16/include
/usr/local/include
/usr/include/wasm32-wasi
/usr/include
End of search list.
Note how /usr/include/wasm32-wasi/c++/v1 is missing.
