Hi,

I try to refresh amneziawg-linux-kernel-module to 3.1.20260812 in Guix but it fails on build time with the following error:

error: in phase 'build': uncaught exception:

Common "fix" for GCC strictness would be to provide CFLAGS:

"CFLAGS=-g -O2"
" -Wno-error=implicit-function-declaration"
" -Wno-error=implicit-int"
" -Wno-error=incompatible-pointer-types"

But current Make file does not support it for some reason.
