there's a reason behind this....despite the fact that glibc is made to
be independent of the kernel headers, the glibc developers stupidly
insist that /usr/include/linux contain the headers for the version of
the kernel used to compile glibc. of course this is horribly wrong and
breaks all kinds of things, and it's not at all necessary. of course
this isn't the first time they've been incompetent, and it certainly
won't be the last... when you have a core system component that grows
exponentially with each release, something is fundamentally wrong.. :(
