Dear Simon,
Of course I have read the MS docs, especially:
http://msdn.microsoft.com/en-us/library/2kzt1wy3.aspx
which says, that /MT uses the multithread, static version of the
run-time library.
As far as I understand this is not what most people want since to my
knowledge most programs seem to use the /MD option.
I also know that option /MT works pretty well for source code of
R-packages compiled for Windows XP. My second question is if it will
also work with Windows 7 which I do not have yet.
Furthermore, you may have realized that since some time I am trying to
find out why in my case neither option works on Vista, see my more
detailed question at:
https://stat.ethz.ch/pipermail/r-devel/2009-September/054843.html
If you have any idea in this case I would appreciate it very much.
Best regards
Christian

Dear Duncan,
In your document "readme.packages.txt" you have a very helpful
chapter on "Using Visual C++".
Please allow me to ask you one question: Why do you propose the
option "/MT" instead of option "/MD"?
(To my knowledge usually option "/MD" is used when compiling programs
with VC++.)
Have you read the MS docs? They have different purposes - /MD pulls in
MSVCR which may not be what you want (depending on your code), /MT
just says that you want thread-safe libs. The fact that something is
"usually" used is not necessarily a very good indicator -- it's better
if you know what you're doing ;).
Cheers,
Simon
