bug#6547: GNU coreutils 8.5 "make check" => tests/test-suite.log 8 of 365 tests failed

[Paul Eggert]

This problem could well be because coreutils at some point uses
fchmod(4, 0100644) in that test case, and your version of NFS
might not take too kindly to that leading "1".  Is this something
that you can debug interactively?  For example, can you do this
in a fresh directory:

+ mkdir -p a/b/c a/b/d e
+ touch a/b/c/foo a/b/d/foo
+ cp -p --parent a/b/c/foo e

except that you run that "cp" under GDB, and put a breakpoint
on fchmod_or_lchmod, and see what happens if you manually
AND out that leading "1" bit?
