Hi,

building coreutils 8.12 on a Linux 2.6.25.20, glibc 2.8 machine, "make check"
shows these lines:

  ./misc/pwd-unreadable-parent: skipping test: can't use buggy system getcwd
  SKIP: misc/pwd-unreadable-parent

REPLACE_GETCWD is indeed 1, because the test from m4/getcwd-path-max.m4 failed:

configure:26992: checking whether getcwd handles long file names properly
configure:27154: gcc -m32 -march=i586 -std=gnu99 -o conftest -g -O2 -Wall -I/arch/x86-linux/gnu/include -m32 conftest.c  >&5
configure:27154: $? = 0
configure:27154: ./conftest
configure:27154: $? = 12
configure: program exited with status 12

But is that known and expected that glibc 2.8 getcwd() does not handle
long file names??? And yes, I do have /proc mounted and readable by everyone.

I've pushed that, so am closing the ticket.
Thanks again.
