Package fakechroot fails to build with GCC 14 because of various C99
violations which previously just generated warning s but which cause
errors with GCC 14 by default.  For more information see
https://gcc.gnu.org/gcc-14/porting_to.html and meta bug #1220571.

BuildService failures are available online at:
https://build.opensuse.org/package/live_build_log/home:rguenther:plgrnd/fakechroot/openSUSE_Factory/x86_64

The build with GCC 14 can now be tried locally with:
osc build --clean --alternative-project home:rguenther:nextgcc

The (first) error that stops the build is:
