The files have only been touched by a subset of three people: pdknsk, Philip Withnall, and Marc-André Lureau. Their copyrights are assigned to pdknsk, Endless OS Foundation and Red Hat. The default license for GLib at the time of writing these files was (and still is) LGPL-2.1-or-later. `driver.c` came from LLVM and is under a different license: https://github.com/llvm/llvm-project/blob/main/compiler-rt/lib/fuzzer/standalone/StandaloneFuzzTargetMain.c. That doesn’t affect the license of GLib overall, since it’s only used for testing during development. Signed-off-by: Philip Withnall <pwithnall@endlessos.org> Helps: #1415
