[Bug libc/2417] New: getcwd() uses ENAMETOOLONG instead of ERANGE


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.
