"make headers_install" modifies the kernel header files to be usable from userspace. For example, they may declare "char *p" as "char __user *p" which means the address is in userspace instead of kernelspace. This is important from kernel, but it has no meaning for userspace. So "make headers_install" removes "__user" simply. All the changes by "make headers_install" should never affect glibc, gcc, etc. So you don't have to rebuild them. You can just keep using it. Of course it depends upon what "different kernel headers" means. In case of different architectures including 32/64 bit, you need to rebuild and use the correct version. J. R.
