Clang 16 makes implicit int and function declarations an error by default in any mode except for C89. The configure script has two of these that cause it to misdetect features when using Clang 16. * Implicit `int main` in the errno check. This is fixed by adding the missing `int`. * Implicit definitions of `opendir` and `closedir`. These are fixed by including the required headers.
