Much better, thanks. Two minor nitpicks: return is not a function,
so I prefer return x to return (x). Functions and function calls
should have their opening parens directly following the function
name (unlike loops etc. where we use a space). But don't bother
changing it unless you feel really motivated :)

This doesn't compile with old gcc versions. Unlike the kernel we still
support gcc-2.95 (I think), so please make sure you have no declarations
after statements.
