I see that, for example, msoul...@anton:~$ equery belongs /usr/include/linux/quota.h [ Searching for file(s) /usr/include/linux/quota.h in *... ] sys-kernel/linux-headers-2.6.23-r3 (/usr/include/linux/quota.h) ul...@anton:~$ uname -a Linux anton 2.6.25-gentoo-r8 #9 Sun Nov 23 19:14:08 EST 2008 i686 AMD Athlon(tm) XP 1700+ AuthenticAMD GNU/Linux So slightly off but compatible. At some point a newer glibc would simply fail to build if it's incompatible then, I assume? Looking on a CentOS box I see that they package that directory in a package called glibc-kernheaders.
