[Message part 1 (text/plain, inline)]

Hello Janneke,

Attached a patch to relax gcc-14 for rumpkernel for core-packages-team. It might be not be needed with the 20250111 tag but I have not found the patience to look into updating it.

It overwrites HOST_CFLAGS which are -O by default. Let me know if you want to add the -Wno-implicit-function-declaration instead of replacing.
