Thanks for the patch. However:

- The problem also occurs with GCC 13.x, so it's not a GCC 14.x issue

- On my side, I also have build failures like this:

  svgint.h:40:9: error: unknown type name 'xmlParserCtxtPtr'
   40 | typedef xmlParserCtxtPtr svg_xml_parser_context_t;
      |         ^~~~~~~~~~~~~~~~

  as visible at https://autobuild.buildroot.net/results/895/895fdba2f3fcaa42aa93946f2532351d39b16647/build-end.log

So since the latest release of libsvg-cairo and libsvg was from 2005, I
sent a patch series to just drop both packages:

Thanks!
