Tvheadend

Hello, since this commit:

https://github.com/tvheadend/tvheadend/commit/c0f616e56bc4df70978a060b72f8c6a7ca487d3f

I get the following error when building tvheadend with --enable-ccdebug:

In file included from src/tcp.c:32:

I'm building on Ubuntu Jammy using the following command:

AUTOBUILD_CONFIGURE_EXTRA="--disable-bintray_cache --disable-ccache --disable-pcloud_cache --enable-libsystemd_daemon --enable-libfdkaac --enable-vaapi --enable-nvenc --enable-omx --enable-trace --enable-ccdebug --cc=gcc-12 --cpu=skylake " ./Autobuild.sh -j$(nproc)

Building with --disable-ccdebug works fine. It's the debug version that emits the message and causes the build to fail.
