Forgive me if this is a commonly reported bug, but I wasn't sure if
other discussions on permissions issues were the same as this issue...

$ c:\installs\cygwin\bin\patch.exe -p0 < multithread_utilities_trunk.diff
(Stripping trailing CRs from patch.)
patching file xxx/yyy/zzz/Test.java
...

now attempt to use the files I just patched:

$ mvn clean install
...
[ERROR] error: error reading xxx\yyy\zzz\Test.java;
xxx\yyy\zzz.java (Access is denied)

I was able to reproduce this on another computer, as well.
Windows 7, 64 bit, blah blah blah.

When I right click on the files and go to properties -> security,
somehow all users except administrators have no rights to the modified
files.

Thanks!
