Summary: fCmd test failures on Windows7

Initial Comment:
We are getting test failures for fCmd 9.4, 9.6, 9.9 and 9.11 on Windows 7 for both HEAD and 8.5-branch. Each of these uses the testchmod command to set the directory to 555 which seems to equate to 'attrib +r dir & cacls dir /e /d Everyone' ie: set the directory readonly and deny write access. Presumably on Unix a 555 directory can be renamed or otherwise modified by not on Win7. The actual error is a permission denied when trying to rename the directory.
So I think this test is wrong here. I believe the ACL being set is probably overly restrictive if we are trying to emulate posix semantics for directory access with this. But I'm not certain of the intention of the tests in this regard for Windows.
Note: these tests pass on Windows XP. I think they fail on Vista but I have not recently re-checked.

Message:
Given the low portability of this test I've added contstraints to exclude
those that use 555 directories on Windows Vista and above. That leaves them
running on XP.

Message:
It seems to vary. With HFS+ on OSX, I can't rename or delete a dir set to
555, or make, delete or rename files in it. (I can modify existing files
though.) With NFS on Solaris, I can rename the dir (!) but otherwise the
same.

Maybe just mark the tests as nonPortable...
