I've clipped the rest of it, which is more of the same. It can't support the new C compiler construct, and we've managed to break the old ones. Plus it gives lots of warnings that aren't useful and doesn't understand several of the idioms we've started using heavily in the kernel (such as forward struct declaration). Since many of these problems are in the system kernel headers, the break all non-trivial uses of lint. None of these things are ever going to be fixed. It's quite likely the kernel will never again compile on anything older than a c99 compiler. While we have a lot of ifdefs to attempt to support older compilers, it's almost all certainly bit-rotted from lack of use. Warner
