[R] Building R for Windows with ATLAS

I think this is not a R-devel question. Sorry to all if I'm wrong,
please let me know.

I managed to build R successfully with the default BLAS but when I
change the MKRULES to use ATLAS BLAS and set the path to
"C:/cygwin/home/Administrador/ATLAS/lib/WinNT_ATHLONSSE2" I got the
following error message (I'm posting only the final part, there was a
lot of compilation before this):

cp R.dll ../../bin/

The ATLAS BLAS was build using Cygwin. AFTER building ATLAS BLAS I
changed the "Path" variable putting "C:\Rtools\tools\bin;C:\MinGW\bin"
before everything else.
To build R I followed "R Administration and Instalation" and Duncan
Murdoch's guide at http://www.murdoch-sutherland.com/Rtools/,
including the version of MinGW.

At ATLAS web page (http://math-atlas.sourceforge.net/errata.html) I
found the following:

Q: I'm linking with C, and getting missing symbols (such as w_wsfe,
do_fio, w_esfe or s_stop).
R: These kinds of symbols are Fortran library calls. The problem is
that the C linker does not automatically find the Fortran libraries.
The most common fix is to either link using your fortran linker, or to
rewrite your code so that Fortran routines are not called. If you know
where they are, you can also choose to link in the Fortran libraries

Well, I can understand that there is a huge probability that this is
my problem. Unfortunately I know nothing of C or Fortran. Even if I
knew that I have these Fortran libraries I wouldn't know how to link
them. I tried to look at MinGW web page but found nothing.
Any help would be mostly welcome, please.

Sorry for English errors and lack of knowledge. I hope I made myself
