Fails to build with GCC 14

On macOS it fails already at configure:

Exit code: 1

Which happens because -no-cpp-precomp is not accepted by any recent versions of gcc:

configure:13359: ccache /opt/local/bin/gcc-mp-14 -o conftest -pipe -Os -arch ppc -no-cpp-precomp -fno-common -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include -I/opt/local/include -L/opt/local/lib -Wl,-headerpad_max_install_names -arch ppc conftest.c  -L/opt/local/lib -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl >&5
gcc-mp-14: error: unrecognized command-line option '-no-cpp-precomp'

-no-cpp-precomp works with gcc-4.2, but should not be used with modern ones.
