Subject: [PATCH] [Clang 15.0.1] Downgrade implicit int and implicit function
declaration to warning only
The changes in Clang 15.0.0 which enabled these diagnostics as a warning which defaulted to an error caused disruption for people working on distributions such as Gentoo. There was an explicit request to downgrade these to be warning-only in Clang 15.0.1 with the expectation that Clang 16 will default the diagnostics to an error.
See https://discourse.llvm.org/t/configure-script-breakage-with-the-new-werror-implicit-function-declaration/65213 for more details on the discussion.
