Building WPE with libwebrtc and GCC 12, I get the following build failure:

Source/ThirdParty/libwebrtc/Source/third_party/abseil-cpp/absl/strings/ascii.cc: In function ‘constexpr void absl::ascii_internal::AsciiStrCaseFoldLong(absl::Nonnull<char*>, size_t)’:
Source/ThirdParty/libwebrtc/Source/third_party/abseil-cpp/absl/base/optimization.h:265:23: error: ‘unreachable’ is not a member of ‘std’
  265 |     if (!(cond)) std::unreachable(); \
      |                       ^~~~~~~~~~~
Source/ThirdParty/libwebrtc/Source/third_party/abseil-cpp/absl/strings/ascii.cc:205:3: note: in expansion of macro ‘ABSL_ASSUME’
  205 |   ABSL_ASSUME(size >= kCaseFoldThreshold);
      |   ^~~~~~~~~~~


This is fixed in abseil-cpp upstream in https://github.com/abseil/abseil-cpp/commit/a305e859b6d0abe6d88a3fe12c6891152cc6e859
