access() call as a su

[Ivo Welch]

On Mach, a BSD 4.3 clone with a gcc compiler:

I am trying to establish if a file has the executable  attribute set. access()
works just fine if I am not  the su, or if  I su name. However,  if I just su,
(i.e. become root), all files appear to access() to be executable.

Is this a bug on my machine, or am I doing something wrong?
