[Rd] Building R v2.1.1 for Windows

[Erich Neuwirth]

Recently, I notice strange things when I try to build R 2.1.1 on Windows XP.
I downloaded and unpacked. R-2.1.1.tar.gz.
All the tools are in place.

I get as far as building the installer, and then the following happens:

perl JRins.pl rw2011 rw2011
"C:/Program Files/Inno Setup 5/iscc" R.iss > rw2011.log 2>&1
make[2]: Leaving directory
`/cygdrive/c/devel/R/R-2.1.1/src/gnuwin32/installer'
make[2]: Entering directory
`/cygdrive/c/devel/R/R-2.1.1/src/gnuwin32/installer'

rm -rf R.iss Rsmall.iss *.log rw2011
rm: cannot remove directory `rw2011/library/base/html': Directory not empty
rm: cannot remove directory `rw2011/library/tcltk/Meta': Directory not empty
make[2]: *** [clean] Error 1
make[2]: Leaving directory
`/cygdrive/c/devel/R/R-2.1.1/src/gnuwin32/installer'
make[1]: *** [rinstaller] Error 2
make[1]: Leaving directory `/cygdrive/c/devel/R/R-2.1.1/src/gnuwin32'
make: *** [distribution] Error 2

Looking into the two supposedly nonempty directories
I see that in fact that are empty.
Of course, I only can look a little bit later, so this might be a timing
issue.
Has anyone experienced similar problems?
This effect is somewhat random. The supposedly nonempty directories
change from build attempt to build attempt.

So far, this has not happened when I build R-patched and R-devel which
I update from SVN.
