R devel - Apr 2013 - package file permissions problem R 3.0.0/Windows OS

Dear list members,

I'm experiencing a file permissions problem with a package built under
Windows with R 3.0.0. I've encountered the problem on two Windows computers,
one running Windows 7 and the other Windows 8, and both when I build the
package under RStudio or directly in a Windows console via "R CMD
build".

In particular, the cleanup file for the package, which as I understand it
should have permissions set at rwx-r-r, instead has permissions rw-rw-rw.
I've attached two .png screen shots showing how the permissions are set when
the package is built under R 2.5.2 and R 3.0.0. 

I think that my two Windows systems are reasonably vanilla. Here are the
system and session info from R 3.0.0 run from a Windows console:
> Sys.info()
                     sysname                      release
                   "Windows"                      "7 x64"
                     version                     nodename
"build 7601, Service Pack 1"              "JOHN-DELL-XPS"
                     machine                        login
                       "x86"                       "User"
                        user               effective_user
                      "User"                       "User"
> sessionInfo()
R version 3.0.0 (2013-04-03)
Platform: i386-w64-mingw32/i386 (32-bit)

locale:
[1] LC_COLLATE=English_United States.1252
[2] LC_CTYPE=English_United States.1252
[3] LC_MONETARY=English_United States.1252
[4] LC_NUMERIC=C
[5] LC_TIME=English_United States.1252

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

I have the latest Rtools30 installed and on my path:
> Sys.which("tar.exe")
                   tar.exe
"c:\\Rtools\\bin\\tar.exe"

Is this a general problem or is it possible that there's something about my
Windows configurations that's causing it?

Any information would be appreciated.

John

POSIX-style execute permission isn't a Windows concept, so it was 
fortuitous this ever worked.  One possibility is that Cygwin was 
involved, and a Cygwin emulation got set when tar unpacked the file and 
converted back to the tar representation when Cygwin tar produced the 
tarball. (The tar in Rtools is a fixed version of Cygwin tar, fixed to 
use Windows file paths.)

What are those screen shots of?

R 2.5.2 was a very long time ago.  A recent change is

     ? R CMD build by default uses the internal method of tar() to
       prepare the tarball.  This is more likely to produce a tarball
       compatible with R CMD INSTALL and R CMD check: an external tar
       program, including options, can be specified _via_ the
       environment variable R_BUILD_TAR.

Can you try using an external tar?  (Using the internal tar on Windows 
was first trialled in 2.15.3.)
