This is an argument I have heard several times, but I never understood: If this risks breaking binary compatibility, then your kernel (compiled with its own headers, after all) might not be binary compatible with your glibc.

This is when you compile modules for the current kernel, a prominent example being MOL. -- Martin ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
