Hello @matthiaskrgr

Thank you for this report The maybe_unused is part of the C23 standard, and while it is not supported for clang-15, clang-17 has it:

0.21 [jack:~/git/duperemove] clang-17 -DVERSTRING=\"v0.12-27-g0e27-dirty\" -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -DIS_RELEASE=0 -c -o duperemove.o duperemove.c

That version is currently in rc and should be release in september 2023

LLVM 17 has been release as planned

This project can now be fully compiled using make with this version
