A call to getcwd() with a buffer smaller than the actual path returns an error
ENAMETOOLONG on all architectures but ia64, whereas POSIX and the *GNU libc
manual* say ERANGE. Actually this is the value returned by the kernel.

IMHO the kernel has to be fixed, but the GNU libc should also correct the
number. That's the purpose of the attached patch.

When you say "on all architectures but ia64" do you mean this is true for the
generic kernel or is this Debian specific? On OpenSUSE x86 10.0 I get ERANGE.

I do not see why glibc should put in a patch to work around a bug in the kernel.
This bug should be fixed in the kernel only. If glibc put in a workaround for
every simple kernel bug which code be fixed the code would quickly become
unmanageable.

There is no problem in libc and I cannot see anything wrong in the current
kernel sources either.
