Bug report

The PTHREAD_SCOPE_SYSTEM configure check lacks int before the main() definition and causes Clang to emit a -Wimplicit-int warning. This warning becomes an error by default with Clang 16+.

Your environment

• CPython versions tested on: master
• Operating system and architecture: Gentoo Linux amd64
• Clang 16 (or Clang 15 with -Werror=implicit-int -Werror=implicit-function-declaration)
