Summary0000486: Contradictory comparison of link() and linkat() behaviors
Description"If linkat() is passed the special value AT_FDCWD in the fd1 or fd2 parameter, the current working directory is used for the respective path argument. If both fd1 and fd2 have value AT_FDCWD, the behavior shall be identical to a call to link()."

Since the latter sentence is not predicated upon the value of flag, my reading of this is that both linkat(AT_FDCWD, path1, AT_FDCWD, path2, 0) and linkat(AT_FDCWD, path1, AT_FDCWD, path2, AT_SYMLINK_FOLLOW) should be identical in behavior to link(path1, path2), which is impossible since flag==0 and flag==AT_SYMLINK_FOLLOW specify different behaviors.
Desired ActionChange

  "If both fd1 and fd2 have value AT_FDCWD, the behavior shall be identical to a call to link()."

to

  "If both fd1 and fd2 have value AT_FDCWD and flag has an implementation-defined value of either 0 or AT_SYMLINK_FOLLOW, the behavior shall be identical to a call to link()."

This is closely related to 0000326 which is being fixed in TC1.
It would be good if this additional aspect of the problem could be
addressed by updating the resolution of 0000326, so that the
change can be included in TC1.
