[R] R CMD SHLIB gives error: bad value (generic) for -mtune= switch

[Prof Brian Ripley]

This is clearly a compiler configuration error, not an R error.  I note 
that you have c:\Rtools\MinGW\libexec\gcc\mingw32\3.4.5 in your path, 
which is *not* part of the instructions for R 2.6.0.  Please try again 
without it.
