R help - Aug 2009 - Building 'R' from source for Windows.

I know I am going to catch alot of comments for this question but I am really
stuck. If there is some written documentation that I have missed please redirect
me.

I want to build 'R' from source on a Windows Platform. The main reasons
are that I want to check out a debugging some existing packages so I need to
build with debug symbols and I want to check out a 64-bit version of
'R'. So I read the instuructions and downloaded and installed
'rtools' and extracted the source. Then I ran into this statement in
R-admin.pdf:
>Open a command window at ?R_HOME/src/gnuwin32?. Edit ?MkRules? to set the
>appropriate paths as needed and to set the type(s) of help that you want

But when I go to this directory I don't see MkRules. In fact I don't see
any files, just folders (bitmap and unicode). Are the instructions wrong ? Have
I missed a step? Or is there somewhere I can retrieve the missing file
(MkRules)?

Thank you.

It should be there. Three possibilities:

- Your editor is not showing it because of extension issues (look for 
"All files")

- You are misinterpreting R_HOME as something other than the source 
directory. (Could this be a typo? R_HOME is usually the destination dir, 
but source is what makes sense here. Or are the instructions assuming 
builddir=srcdir=destdir?)

- You unpacked it incorrectly or got the wrong source file. I checked 
http://cran.r-project.org/src/base/R-2/R-2.9.1.tar.gz and it does have 
the file in the right place.
