Reproduction of isoc23 compilation failure.
$ git clone https://github.com/greenfork/isoc23.git
$ cd isoc23
# Wait a bit because this command downloads a large Raylib repository!
$ git submodule update --init --recursive jaylib
# Add janet.h to the hardcoded in jaylib include path (remember to delete it afterwords)
$ sudo mkdir /usr/local/include/janet
$ sudo cp src/janet.h /usr/local/include/janet/
$ zig version
0.11.0
$ zig build # works fine
$ zig build -Dtarget=x86_64-linux-gnu # fails
