tar-1.26 not unpacking archives with symlinks?
 
Hi, I'm hitting an error when trying to unpack archives with the
recently unmasked tar-1.26. Basically any symlinks in the archive
trigger an "unknown file" error. This prevents me using emerge -k
amongst other things


I only see this on uclibc-0.9.33 based system, not on the build host
which uses glibc amd64


Can anyone else repro this and shed any light on what the problem might
be? Problem in tar or uclibc?


Thanks

Ed W

fchmodat() is a syscall that takes 3 args. uClibc was providing a stub that
treated it as 4. i fixed things up, so if you want to try with the fix i just
committed, that'd be nice ...
