Torvalds is grumpy because some new code added to the IPv6 subsystem has created conflicts. "The conflict I get is due to stupid new gcc header file crap," he writes. "But what makes me upset is that the crap is for completely bogus reasons." The new improved code uses fancy stuff that wants magical built-in compiler support and has silly wrapper functions for when it doesn't exist. Linus provides an alternative that contains a single and understandable conditional, which looks cleaner and generates better code.
