hello with: ./configure --without-ns --with-x-toolkit=no -with-native-compilation --with-mailutils which is not what I really wants, we’re back to the original failure: checking libgccjit.h usability... yes checking libgccjit.h presence... yes checking for libgccjit.h... yes configure: error: The installed libgccjit failed to compile and run a test program using the libgccjit library; see config.log for the details of the failure.
