This is with cygwin-1.7.

------- Comment #2 from billingd at gcc dot gnu dot org 2009-01-24 07:41 -------
This looks like a problem with the access function on cygwin-1.7
$ touch foobar_file
$ chmod a-w foobar_file
$ cat test_access.c
#include <stdio.h>
#include <unistd.h>
int main (void) {
char *file="foobar_file";
int m = W_OK;
printf("access = %d\n",access(file,m));
}
$ touch foobar_file
$ chmod a-w foobar_file
Under cygwin-1.5
$ ./test_access
access = -1
Under cygwin-1.7
$ ./test_access.exe
access = -1

I asked about this on the cygwin list.

The reply was:
I assume you mean "access = 0" under 1.7. If that's what you see, the
test probably works as designed. You're running the test under an
administrative account. Admin accounts have always the right to write,
same as under Linux.
... and my account has Local Administrator rights.

------- Comment #4 from billingd at gcc dot gnu dot org 2009-01-29 22:14 -------
Tests gfortran.dg/chmod_2.f90 and gfortran.dg/chmod_3.f90 also fail.
There is also some discussion at
http://gcc.gnu.org/ml/fortran/2009-01/msg00353.html
In each case, the failure is due to the test
i = chmod (n, "a-w")
if (i == 0 .and. getuid() /= 0) then
if (access(n,"w") == 0 .or. access(n,"W") == 0) call abort
end if
The problem is that users with Administrator rights can always
write to files - similar to root on unix - but it is not easy to test for this.
I will prepare a patch that moves the parts that fail to a new test that is
UNSUPPORTED on cygwin.

The posted patch seems wrong, since the test is testing chmod you should use
stat to check the result.
