more new test failures on Darwin

[Jack Howarth]

FX,
   I built the current gcc trunk on Fedora Core 5 linux and can reproduce
the same problem. The chmod_1 test program aborts when run through sudo.
The code that is causing the abort is...

  call chmod (n, "a-w", i)
  if (i == 0) then
    if (access(n,"w") == 0 .or. access(n,"W") == 0) call abort
  end if

The other portions of the test seem to run fine. The chmod_1.f90,
chmod_2.f90 and chmod_3.f90 source all abort on the same code
(where chmod attempts to change the write access of the file)
when run through sudo.
