Ok, thanks you both for your replies, i would expect the headers to be
upgraded together with the kernel.
But, you both say that a complete reinstall is recommended when
upgrading Glibc, but I guess you both don't have Graphical desktop
(X+KDE) and heavy programs (OOo) installed?
I mean, if I upgrade glibc from 2.5 to 2.6, should I reinstall X, KDE,
OOo and about 500 optional dependencies for X and KDE??
If so, I won't even think of upgrading glibc :P
