I updated my system yesterday. I then tried to rebuild virtualbox-ose-kmod.
This fails under llvm15. The same source code built successfully with
llvm14, so I assume that the code has a problem with 15. I suspect that 15
changed some default and declared this as an error, but may be "fixed" with
the proper build option.
Here is the command and error that I see:

Any help appreciated. I really need virtualbox. I think I may force it to
build with llvm14, but I's prefer a fix to build with llvm15.
