Kernel update to 2.6.x.x, do we need a glibc update? - Embedded

Hi,

currently we are running a 2.4.26 Linux kernel on an embedded PPC
machine and a corresponding glibc 2.2.5. Everything works fine.

Now we want to upgrade to a Linux kernel 2.6.x.x.
Do we have to recompile our glibc with updated header files?
Or is the system call interface of the 2.6.x.x backwards compatible to
the system call interface of a 2.4.x kernel?
We want to keep the currently used glibc if possible.


Thanx and kind regards

Can you please eplain your YES? You are of the opinion that the glibc
has to be recompiled? Why? (maybe they do not want to use new features
like NPTL, ...)
