Make hid_kye fails against kernel 6.17.3-1, gcc 15-1.1

[jack-sprat]

Hi,
I previously manually installed v10 from ZIP file (>make, >sudo make install) on OpenSUSE Tumbleweed.
During recent distro upgrade (20251007 to 20251021), I encountered dracut errors reporting failure to find module 'hid_polostar'.
After upgrade and reboot, I uninstalled v10 (>make uninstall); downloaded v13 ZIP, extracted to folder, cleaned v13 (>make clean), and attempted >make; this resulted in error:

Installed version of gcc is 15-1.1

I then tried installing using DKMS (>sudo make dkms_install), mostly because I could then locate make.log - as expected, this also failed - see attached log file:

make.log

I could do with some pointers on whether this is a me issue or a code issue, please?

Is this maybe the same issue as #706 ?
